It Might Just Work

Kevin shares US v Rock Island Armory.

The Central District of Illinois dismissed the charges and the government did not appeal.

Read the whole thing.

It's something.

It's not dicta.

The suits over SBR, SBS, and AOW have a precedent in this case.

Veddy intresting. 

I Can

I can be nice.

I can be polite.

I can never darken the door again.

You tell me how I should just suck up the tyranny, I can just not bother to come by and pay for the goods that keep you employed.

A pity.

I will miss the place.

I Don't Normally Make Popcorn

I cannot wait to see how the protests against immigration in Mexico are different from protests in the USA against immigration.

Because the Mexicans will surely have the moral position and we 'Mercians won't.

I do so love watching them spin hypocrisy in a manner that the normies can spot.

Remarkably Good

GURPS is not a simulator.

It's a tabletop role playing game.

A game.

Yet, it's been remarkably accurate about the effects of firearms.

I've been doing "Will it GURPS?" for longer than I've had a blog because the first two editions explicitly called out a "reality check" and if what you were doing was impossible in the rules, but worked in real life:  Reality trumps the rules!

That, alone, might be why I like GURPS so much to keep dabbling with it despite not playing more than a handful of sessions in 30 years.

My recent dive into .30 Carbine underscored it a bit.

A typical person has 10 hit points.  After taking 10 points of damage, they have to start checking to see if they pass out from the wounds.  After taking 20 points of damage, they have to start checking to see if their wounds killed them.

We have anecdotes of people hitting Chinese soldiers and getting no results from those hits.

I think I've managed to recreate the scenario with the rules.

The cold and underpowered ammo at longer ranges needs many hits to disable a 10 HP person inside the rules and seems to match reports from the battle.

The numbers I have for the underpowered ammo drop .30 Carbine down into pistol cartridge power levels and we have ample examples from police shootings that it can take many hits to stop someone.

The real problem will be breaking it to the players that their ammo is compromised and nobody has any extreme cold experience to tell them they're taking a penalty to their Guns/TL (Rifle) skill.

"Bloody murder!" they will cry!

06 July 2025

That's Kinda Telling

Old Radar Tech dropped some estimated numbers for the degraded .30 Carbine performance and it's spot on the same as .30 Super Carry.

Ouch. 

Probably Still The Aim (Updated To Account For Pi-)


 

I found one, ONE, forum entry claiming that a 1950's lot of Cartridge, caliber .30, Carbine, ball M1 was loaded to 1,600 fps.  Minimum spec. is 1,900; ideal is 1,990.

Update: 1,600 fps drops us to pi- territory

That gives us 3d+1 pi-.  4-19 raw damage with an average of 11 which is halved after penetrating armor.

With a 7% velocity drop because of the cold, we're at 3d pi- (3-18, avg. 10).

Against a normal, human, target that's going to take a few rounds to stop someone with DR 1 winter gear on.  2 to get consciousness and 4 to get death rolls.

Remember, though, out past 330 yards, damage is halved.

That's 2-9 (avg 5) for the 1,600 fps stuff and 1-9 (avg 5) for the 1,488 fps.

That's TEN solid hits, on average, to get to a death roll.

I've found a few anecdotal accounts where troops were engaging at 400+ yards.

You're not going to see your impacts at that range on clothing and with the sights not agreeing with the bullet's path, you're probably not hitting either.

The right drugs will give high pain threshold and the cold will also numb the recipient of the round to cause even good shot placement to the torso to be ineffective.

But let's take them at their word that they saw the impacts and hit where they were aiming.  It'd be blind luck too.  The bullets would be hitting low because of the cold with up to spec ammo and even lower with the underpowered stuff.  7 to 10 inches at 100 yards.  28 to 40 inches at 400.

Even with high pain threshold, an average hit of 11 to the torso will get 10 to penetrate which gets reduced to 5 and that will get the bad guy to 5 HP and they continue to charge!

Nailing them in the vitals will get 30 points delivered and two death rolls.

Past the 1/2D range, though, it will take ten average hits to get a consciousness roll on torso impacts and two to the vitals to get death rolls. 

Now that we've gone through all that...

When did the Korean war end?  1953.

I know a bit about the US Army supply chain and I'm not thinking it's likely that the 1950's vintage ammo that's been tested understrength made it to the troops, even if it was made during the three years of fighting.  The Army tends to FIFO their stuff. 

Probably Just The Cold

Got a comment suggesting that M1 Carbine ammo in Korea wasn't up to snuff.

I can't find the information they're citing, but the looking for it did turn up some interesting stuff about cold weather and ammo performance.

An Army publication for snipers (FM 3-22.10, Sniper (Dec 17) referenced in this link) says the round will impact 1" lower at 100 yards per 20°F the temperature is below the temperature when you zeroed the gun.

FM 3-22.10 pg. 4-147. The change in the point of impact is best determined by referencing past firing recorded in the sniper data book. As a rule of thumb, a 20-degree increase in temperature will raise the point of impact by one minute; conversely, a 20-degree decrease will drop the point of impact by one minute. 

And that's with a spitzer shape, not a round nose; like the .30 Carbine!

Chosin was -35°F and if the troops had zeroed on a nice 75°F day there's a 100 degree difference, or a 5" change of impact at 100 yards.  10" at 200.  15" at 300...

That's assuming the cold soak didn't weaken the springs so bad the hammer doesn't hit hard enough to set off the, now, less sensitive primer...

Norma published a video showing that .30-06 lost velocity as it got colder.


Everything is in Godless Metric.

Room temperature average velocity is 2,625 fps.

28°F ammo is 2,575 fps. (1.9% drop)

0°F ammo is 2,532 fps. (3.5% drop)

Norma specifies 2,772 fps. for this round from a 24" barrel, so we're also seeing the effect of losing 2" of barrel in the test.

2,772 gets us the bog-standard 7d pi from .30-06.

2,625 drops it to 7d-1 pi.

2,575 gives 6d+2 pi.

2,532 gives 6d+2 pi. 

A 3.5% drop in velocity for an M1 Carbine goes from 1,990 fps. to 1,919.5 fps.

That drops it from 4d+1 pi to 4d pi.  Still plenty of energy to penetrate winter clothes.

Losing another 3.5% to get to Chosin temps (baseless extrapolation here) gives 1,850 fps and 4d pi.

With these numbers one cannot help but concur that the troops were missing their targets.

There's a couple of sources that mention the Chinese troops were drugged to the gills.  I've written about another case of bad shot placement and drugged up opponents before: Juramentado

M1 Carbine Vs Armor

The M1 carbine's .30 round cartridge does 4d+1 pi.  That's 5-25 points of raw damage with an average of 15.

According to High Tech p. 64, winter clothing can provide DR 1 at the GM's option.

That will mean that .30 Carbine M1 ball will easily punch it, doing 4-24 points of damage (average 14).

That's certainly enough to knock someone down.

But let's say that a Chinese winter coat is heavier stuff than mere winter gear.

Reinforced padded cloth armor gets DR 2.  3-23 points penetrate (avg. 13).

What about the theory that ice on the outside of the coat somehow provided more protection?

Ice is DR 3 per inch.  So, maybe DR 1 for a good coating of the stuff?  Still getting 2-22 through (avg. 12).

Still enough to get them unconscious if they blow their HT roll on a body hit.

So, I think we can say that all those troops were missing their shots rather than doing damage.

Even the rare hit on the web gear or ammo pouch doesn't account for enough DR to completely protect them with the persistence of the myth.

Shots past 330 yards get half damage.  2-12 (avg. 7) raw.

Even through the heaviest theoretical coat and ice, 0-9 (avg. 4) will penetrate; but 1-11 (avg. 6) is most realistic.  It'd take a couple of hits at that range to drop them, but with the low recoil of the carbine, it's doable.

The M2 carbine will do the same.

Assuming that the damages GURPS, I think we can dismiss the myth that the winter gear of a Chinese soldier in Korea was stopping rounds.

Vids On The Topic

It's been well covered.


Longer version:




05 July 2025

I Thought Orangutans Were Bigger

 I was watching a video about gigantopithecus.

It's a 9' tall, 650ish lb. orangutan.  Maybe 700 lb.

Being the geek I am, I calculated the things ST from its weight.

17 or 18.

How strong is a normal orangutan?

I remember them being a lot larger, like 300 lb. for a male.

Nope.

Just 165 lb. on average for a GURPS ST of 11.  About the same as a chimpanzee.

Gorillas are 400ish lb. and rate a ST of 15 in case you're curious.

Rounding out the great apes is we humans at ST 10.

My Grandma Knows How To Suck Eggs

Please notice the quotation marks around, "the carbine couldn't penetrate a Chinese winter coat."

Why would I put those little bits of punctuation on that?

I'm fully aware that most of those "failures to penetrate" were almost certainly from missing.

It's not an obscure theory.

I'm speculating about the whiz-bang fancy new sights they added after WW2 are to blame because they can be fiddled with.

I've seen people pull the peep all the way to the longest range setting because it sets higher and that makes them easier to see without squishing your cheek down on the stock.

But that also means your shot is going to go high at close ranges.

This adjustment isn't present on the original rear sight.  You get two settings, just like the M16A1.

Then there's the windage adjustment knob.  Get a bored soldier playing with that and forgetting where it was when zeroed and you're missing to one side or the other.

I figured this out on my own because the German winter gear isn't significantly thinner than the Chinese stuff and the Carbine was well regarded enough to retain in service and keep developing after WW2...

Add It Up!

When you get a catalog in the mail, add up the value of all the things you're not buying.

That way you know how much you saved.

If you simply don't buy the things without adding up how much they cost, you're not saving anything, you're just not spending money.

You feel way more smug with a value assigned to it!

Gravel Belly

The gravel belly is sort of the military equivalent to the Fudd.

Its why a bullet-proof rear sight on an M16A1 was changed to a fiddly one on the M16A2.

But it's older than that.

You should see the complicated sights we put on our infantry rifles.

Then go on to not bother teaching the troops how they work.

The people who wanted and needed the vernier caliper quality in the rear sights are people compete on known distance ranges.

As WW2 progressed, we asked the troops if they were using the adjustments in their sights.  We interviewed captured troops.  We exchanged information with our allies.

It was a rare soldier who bothered to adjust the range setting.  It was nearly unheard of to change the windage setting.

So the Army responded by keeping the sights from the Garand and put them on the M14.  Then they added adjustable sights to the M1 Carbine.

Bahwah?

I would love to have God's video tape to see if all those "the carbine couldn't penetrate a Chinese winter coat" were actually misses caused by the rear sight being easily adjustable now and knocked completely off zero by the soldiers absent minded fiddling around with it.

I think things are different now, but I do note that the back-up iron sights we issue all have a range setting and can be adjusted for windage without tools.

A Project

A long, LONG, time ago...

Willard asked me about installing a bayonet lug on an M1 carbine.

When we found out that the front sight needed pressed off we kind of forgot about it.

I stumbled across a pic of an early configuration M1 carbine with a 30-round magazine in it and it reminded me.

So I went out to see what it WOULD take to updated it to the late configuration that's mostly associated with Korea.

Front-barrel band and bayonet lug is $29.

Rear sight is $35.

The tools to remove and install the sights are $100.

Plus taxes and shipping.

Then there's the, mandatory, M4 bayonet:  $150 to $900 depending on vintage and maker.

What amuses me about the project is how many people were converting their carbines from the later configuration to match the WW2 one.

Representative Sample

Wading into the CMP 1911 pond again...

The lifetime limit has been increased from one to four.

While I defend the idea of buying one for the provenance, I just can't justify four to myself.

This is where I start agreeing with some of the objections and evoke "mixmaster."

It's not a case where you can get one of each maker because the parts were scrambled several times since 1945.

I'm not in the two is one and one is none frame of mind with pistols I obtain for the having, not the using.

But every one of the three I have left in my limit is one more available to someone who wants that single example.

If I were to get another .45 Gov't Model, I'd get a blue one.

I still need me a 10mm example.

PS: Someone checked the market and $1,700 is about where the $1,200 condition guns are trading.

Make Up Your Gorram Mind

GOA emailed me bragging about what we got from the Big Beautiful Bill® the other day, how it was their goal from the start and how happy we should be about it.

Today they share a video from VSO Gun Channel that's complaining about being stabbed in the back by the Republican Party.

For fuck's sake, pick a fucking lane!

It's OK to say, "This is what we hoped to get, we didn't get it, but we got something and what we got, while not perfect, is at least a step in the right direction."

GOA has never understood how the sausage is made.

No compromise strikes again?

I'll take the incremental win.

A $0 tax plus registration lays the groundwork to have it declared unconstitutional because its entire legality hinges on it being a tax.  $0 is not a tax.  Sucks that it's going to take FOREVER to get it through the courts, but...

39 Years Old

GURPS was initially released this day in 1986.

FuzzyGeff and I bought our copies a bit later.

We didn't play it long because the 2nd edition was released less than a year later on June 2, 1987.

I played 2e a bit longer than many because 3e didn't make it to the AAFES bookstores while I was stationed in Germany.

But 2e lasted just longer than a year before 3e was released on August 18, 1988.

3e lasted 16 years and one day if you don't consider 3eR being released on July 7, 1994.

Some Other Circuit

A pro gun ruling came out of the 5th circuit, again.

I don't live in the 5th circuit, so telling me what a great deal it was doesn't really matter.

I live in the 11th.

While you're celebrating, could you, maybe, explain why this is good for the rest of us outside the 5th?

Because, as I read it, this is a circuit split on 18-20 year olds owning guns and we have the 5th saying 18+ can own and the 4th and 11th saying, "gotta be 21." 

Are you alluding to this circuit split means its more likely that SCOTUS will take up the case?

Stop alluding and say it then?

I'm happy for the residents of the 5th circuit, but you have GOT to stop acting like victories that don't affect a rather large population matter to us.

Not a lot is being done for Florida by the pro-gun forces and it's getting stale reading about how great it is elsewhere. 

It's Not Raining

Dear GOA:

Getting the tax on, some, NFA items knocked down to $0 while keeping the registration and enhanced background checks is a, mostly, good thing...

It is not a major victory for our rights.

It is NOT what you set out to accomplish.

You bragged about how you got the language for full removal of short barrel rifles & shotguns and suppressors into the Senate version of the bill before the parlimentarian squished that plan.

Now that we have crumbs rather than cake you're bragging like this was what you planned all along?

Gods it ticks me off the way you guys try to communicate. 

So Basic

Having a bit of a tiff with someone on Arfcom over basic dimensions.

A basic dimension is one without a tolerance.  No plus, no minus, it is what it says to infinite decimal places.

Most of the time that dimension exists as a datum for other dimensions.  Those dimensions have tolerances so the thing you're making can actually be made.

This person mentions this, but goes off on how you can never hold the basic dimension without some kind of tolerance on it.

To that I say bullshit.

I've worked places that held them on mass produced items.

I will say that you shouldn't use them unless that dimension is critically important.  It's expensive to set up to hold such a dim and uses more resources from quality control to assure it's being held.

But I did like him explaining to me my job for over 16 years.

Incorrectly?

Andy Richter predicts that people will use MAGA in 20 years like we use Nazi today.

Do you mean to label anyone you don't like who opposes the Democrat party line?

President Republican is LITERALLY MAGA?  Like that?

Because you dancing monkeys have so overused Nazi that I'm not even sure that Hitler was literally Hitler any more.

I do remember how you slandered the Tea Party people as racists, so I don't think I'm going to listen to you.

That's still not listening to you, Andy.  Your opinion never mattered.

More Guac Please Perhaps On Toast

The greenies have decided that avocados are now haram, I need to include them more often in my diet.

Which is great because they're good for me and I like them!

Another Damn Lies With Statistics

Remember that graph that showed how hot The Gulf was that compared a really recent average to a range starting in 1878?

There's also some swelteringly hot years before that cut off as well.

I can't imagine a meteorologist not knowing that.

If you're going to figure a mean you need to use the entire range!

Wanna bet if we use the records going all the way back to the 1600's that the Spanish were keeping that we're going to find that it's not really that much hotter today than it's been historically?

I Remember When

Remember when we didn't need to read the 2,400 page Obamacare bill and would have to wait for it to pass to see what's in it?

Now a 940 page reconciliation bill needs to be read in whole so...

They're emphasizing how big this bill is and forgetting the multi-thousand page monstrosities they shoved through in the past.

R and D operate to different standards.

Won't Someone Think About The Strippers?

The "No Tax On Tips" bill excludes independent contractors.

Most strippers are independent contractors.

This is fundamentally unfair!

Moar Schoolhouse Rock


The differentiation between noun and pronoun is baked into the language.

Whether you like it or not.

The Schoolhouse Rock vid in the post below explains why they exist.

The usual suspects, in their shrill attempts to blur gender pronouns created a position where they wish to use no pronouns.

And I used two pronouns in that sentence to talk about them...  Did it again!

Pronouns are inescapable if you're still speaking English.

I find it very odd that someone whose job is writing doesn't understand English this hard.

But it's possible that as a game designer, they (<--pronoun!) think that all the rules are mutable because they certainly are when you're designing a game.

Shit I Didn't Notice Before

Tonight I made Harvey stop talking for a second so I could parse the tempo of the bangs to decide if it's gunfire or fireworks.

Shocked Shocked I Say

Steve Jackson Games hires the lead designer from Possum Creek Games, Jay Dragon.

Possum Creek Games becomes an imprint of SJ Games.

All of the new game announcements are for old Possum Creek IP.

Who could have predicted this?

PS:  Jay Dragon doesn't use pronouns.  So if you have to talk about Jay Dragon, I guess you have to use the full noun.

PPS: Here's a simple lesson in WHY we fucking use pronouns, Jay Dragon.

I AM An Expert You Know

D-P-355a refers to a set of drawings.

Rock Island Arsenal last updated them in 1960.


This is some OLD SCHOOL drafting!  They don't make drawings like this any more.  They didn't make drawings like this when I was still drafting.

Of note is the use of geometric tolerancing.  That was state of the art in 1960.

I'd suspect (guess) that Rock Island was told to take the 1928 prints that all M1911A1's were made to and get them up to current engineering standards in case war were declared.

Now, this print tells you WHAT to make, not how to make it.  The processes of how to make this part to this print is called a "technical data package".

Colt, historically, has been VERY reluctant to part with that documentation.  In WW2 they basically had to be forced to give it up.  Even so, Remington Rand lost almost a year's production of parts that were nominally to the print, but wouldn't interchange with other makers guns.

Mil Spec vs Commercial

I remember talking with New Jovian Thunderbolt when he took a 1911 armorer's class and his talking about fitting parts to a gun.

I was reminded of:

D-P-355a 3.3.2 states, "Interchangeability. Unless otherwise specified on the drawings, all parts shall be interchangeable. Pistols and repair parts shall be capable of meeting the interchangeability tests specified in 4.3.3.4 and 4.4.4 (In normal assembly operations there shall be no objections interposed to preferential assembly of parts provided that all parts are dimensionally acceptable.)"

One thing, in particular stuck out and that was the ejector.  It's retained by a notch in the ejector by a pin in the frame.

He described all the careful measuring to properly locate and align that notch in a virgin ejector.

In the Army TM the procedure was to secure the frame in a drill press, install the ejector and drill it in place; effectively using the existing hole in the frame as a fixture.

I am often curious about parts interchange among all the 1911 clones out there.

I know I've watched a lot of vids about how to fit a safety because I'm considering changing the style on my .38 Super.  The safety is one of the drop-in parts on a mil-spec M1911A1.

Software Janitor has spoken of fitting a barrel to a slide once or twice. 

27 June 2025

Thanks Cellular Provider

We don't have an unlimited plan for our cell phones.

When three out of the four phones on the plan go out of state, we use up our data.

We know how much the overages cost and we brace for it.

But the phone company keeps telling me I'm over and it's $20 a gig and I should change to an unlimited plan...

Which would be a whopping $20 a month more for all four lines.

The thing is, we only go over like once every five years.

So $160 or so every five years or $240 a year for the same five years?  (That's $1,200 for you liberal arts majors).

Thanks, but we got this. 

Coming Up Short

The Senate parlimentarian squished our hopes at sneaking the removal of suppressors and short guns from the NFA.

I am not shocked at all. 

Every Single Time

Every single time I've mentioned the CMP is selling M1911s, someone just has to mention you can buy a new one for what the CMP wants.

It's an odd psychological compulsion.

I should have finished my degree and gotten a job in academia to get a grant to study it.

It happens with cars quite often as well.

It's Just Me Isn't It

Do you lock up your guns so that your choice is limited to the gun you assigned home defense duty?

So that if you do need to defend your house you're not dithering about which gun to use?

Just me?

Again? 

Reluctance

I am making no progress on some gaming fronts and it hit me why.

I'm not going to get to use what I've figured out.

The incentive to finish it is gone knowing that there's no players.

Not even players I've never met running a game with a GM that isn't me.

Doing it in GURPS means that 99.9% of TTRPG people reject it immediately.

The group I played with before I moved to Florida abandoned GURPS pretty much as soon as my taillights were hidden by terrain.

My hand has hovered over the "delete" button on my gaming folder on the hard drive more than once.

I like playing around with it, but it's become random here and there.

FuzzyGeff doesn't even seem interested in talking about it anymore.

He's moved on to Pathfinder.

C'est La Vie.
