[QUOTE="Turpentine21, post: 2713252, member: 124909"] In a bolt action rifle it is very easy to get your headspace and resize your brass accordingly. Just bump it back till it barely closes with a touch of resistance. Turn the die in maybe 1/8 of a turn, and you should be good. I sometimes use a Lee Collet and a body die for 308. Now I just use an RCBS X Die. I have on military brass had to remove material from the shell holder to get the appropriate headspace. I measure constantly. There are probably six sets of calipers on my bench for various reasons. Length of case, OAL, COAL, Base to shoulder with appropriate comparator insert, base to ogive with insert, neck tension, neck wall thickness, web expansion, etc. The 1st thing I do when I shoot a new rifle is take whatever brass I just shot, examine it, and measure each one to the shoulder, take the average, and write it down in my journal along with that rifles information. If you are not measuring base to shoulder with a comparator on a semi auto, there is a very good chance that you are working your brass too much or will wind up with a round stuck in the chamber. Particularly if carbon builds in the chamber. I saw that just last week with a guy running wolf bullets and a suppressor. Something as simple as not enough lube on the neck when the expander ball pulls back up and through can stretch a case out of spec and cause it not to chamber. Been there, done that, got the t-shirt. Then again, over the last 35 years of loading for shotgun, rifle, pistol, and spitball. I’ve accumulated my share of t-shirts [/QUOTE]
