Weren't barrels roll stamped after all the boring, threading, chambering, etc. was done? Big mystery as 7mm barrels weren't made at Chicopee were they?
I have no idea what order they were done in. I was just going with KISS.
If Fireball was inferring that maybe they took an old 250-3000 barrel with 1-14 twist and rebored it to 7mm and chambered it for 284, don't see that as being impossible.
But that raises the question of when in the process did they thread the barrel? Chicopee Falls threading was different than Westfield. Would they have had a bored and stamped barrel without it being threaded?
