gunsmithing: which steel for blowback bolt?
I've got a 1927a1 that I'd like to make another bolt for. It's .45 ACP,
and strictly a blowback mechanism. Any hints on which alloy of steel to use, and/or what hardness to "shoot" for when heat treating? Seems pretty soft as shipped and the grinder test doesn't seem to tell me there's a whole lot of carbon, but it's been a long time since I've had someone teach mhow to read sparks to guess at alloy. Thanks Dave |
