In keeping with my
"Gonzo Gunsmithing", I'm trying a stepped 7.65 Luger liner in a well-used & abused P-38 barrel...Started last night on the barrel; reaming the barrel itself and milling the breechblock...
So far, so good...This particular barrel is just a 'proof of concept' conversion; the actual barrel I'll use in my shooter is [hopefully!] on the way...
