The parts and production feller is trying to button rifle a barrel. He has been pushing back on some of my info. I just received two emails from 2 friends that are in the business, but with different companies.
That size is exactly what varies from one heat of steel to another heat. In generalities the size before buttoning on a .308 will be around .2992 - .3008. After stress relieving and lapping .0002-.0003 out we want to end up at .3000".
The other:
Bore should be around .2995 or slightly bigger before lapping. Try to be right at or around .3000 lapped.
These guys have been in the barrel business for a lot of years with a couple of the best known barrelmakers. I have emails out to a couple more barrelmakers that I know. I will share what they say to me.
Parts and product guy, I will share what I know and what I can find out for you. I don't have a clue why you are pushing back on this.
