Ok first time doing the Savage Barrel swap.
I have a go gauge and set my chamber up to just barely close on the go guage before tightening the barrel nut. Removed the extractor.
Went and shot 50 rounds, and I happen to have an old Remington barrel in the same chamber (243).
The go gauge sticks out of the Remington by .000" my fired brass by about .025". Which would indicate execessive headspace.
I also took a 40S&W case checked the inside diameter and it is .401, and measured the case length using it. I get (subtracting for the 40S&W case) 1.649 for the fired brass and the go guage is 1.626 (Forrester Go Guage, just checked should be 1.630), again a difference of .023". Using a paperclip I can't feel any seperation inside the case.
I then went to recheck my headspace with a piece of tape on the barrel. If I turn it a 1/2 of a turn (20TPI = .050" per full turn) then that should put me where my brass/remington barrel is telling me. But the Go Guage is now a no-go. Have to keep unscrewing the barrel until I can get the bolt to close, which puts me right back where I started. (I put a piece of tape on all the moving parts before i started).
Gun shot well and was accurate, but what I want to know is do I have a headspace problem and should I not use the go guage to set the barrel headspace, or better yet, what am I missing?
