Yet More On Stellite

And a admonition to myself about making assumptions.

It would have been simple to check, and in fact it was simple to check, once I doubted my assumptions on what "Stellite lined" meant.

The Stellite liner on a US machinegun is the chamber and part of the barrel, not the entire barrel.

It's main purpose is to prevent throat erosion.  That's a bigger concern with machine guns than rifles because of the sustained rate of fire.

Stellite is tough stuff.  So tough that there's a procedure for recovering the Stellite liner from shot out barrels for recycling into new barrels!
