I am chambering a barrel for 338 Federal. Ruger M77 action
I have the barrel trunion, and chamber all set using a Forster 308 Go and NO Go Guages.
Bolt handle drops Totally free on the GO gage, and locks up solidly on the NO GO
Everything felt really good but as a second check before removing the barrel from the lathe I dropped in a live (federal factory) round
It was VERY Tight. I could have forced it close.....but did not
I tried a second live round from box and same result
I pulled the bullet from the Federal Case and tested just the Case with same result
To check my sanity I have a second 308 PTG GO Gage that cleared smoothly
Not sure where to go with this next.
What do I need to learn to make this right? What did I do wrong?
