Chasing The Zero

Went shooting with The Lovely Harvey today.

We did rifles again and she's learning where to put the stock into her RoboShoulder® on her AR and her groups are about half what they were last time we took out her AR.

Huzzah!

I decided to bring Dottie to get the SPARC AR zeroed.

It seemed as if I'd done so at 25 yards, but it was massively high and left at 50 yards.

No problem, just dial the knobs a bit...

I then proceeded to send the group back and forth past the point of aim for another 20 rounds.

The adjustment on the SPARC is coarser than I thought and I was cranking the knobs too far.

The last ten rounds actually went where I wanted, but I was getting irritated and I vertically string when I'm irritated.

It's a known problem and I'm working on it.  Most of the time, I'm successful.
