[QUOTE="VinceMule, post: 2841372, member: 122164"] I form all kinds of cases from 308 Win and 30/06, headstamp means nothing. Also made 6.5x47 Lapua from Rem 22/250, shoots 1/2" at 200 yards in a deer rifle. Made 6 XC from 308 Chinese military brass, PMC 308, and Lake City Match 308, ended up with .400 long necks. I ordered a .275 Piloted neck reamer from PTG, and the gunsmith cut the neck longer in the chamber, then throated it for the 105s. Accuracy with even the Chinese military brass is nothing short of incredible. In my life, I had one mix-up at the range. I was working up loads at the rifle range for a 7 Rem mag and a new 7 STW, alternating guns. I shot a 7 Rem mag in the 7 STW, and ended up with a case neck about 1/4" long, but no problems at all fire forming that case! I never did that again! When I was a teenager, you could buy a 55-gallon drum of Lake City '06 brass for $50. We made everything from 22/250, 243, 6 Rem, 257 Roberts, 8x57, 7x57 from the '06 brass. Annealing with inside neck reaming was a given, later on we neck turned the outside of the necks replacing the inside neck reaming. Back then, inside neck reaming in a custom die was what the talking heads were all preaching. Dad also bought a couple of WWII jeeps in the wood crates to help us kids learn some skills. Revisit the ignition stream of a heavy chamfer inside primer flash hole vs non-chamfer. [/QUOTE]
