[QUOTE="Mark611, post: 715986, member: 49531"] The IVI brass I bought from Top Brass didn't have any primer crimps:rolleyes: I don't know if it was made this way or if they preped it before sale? I have read that some of the Federal and a few other 7.62nato brass is not made with the primer crimp! I chose to use the IVI because it was new brass and I like the heavier walled milspec brass I think it'll hold up better in the long run JMO:cool: and the fact it was cheaper than buying commercial brass. I also have a NM M1A and a GI M1A so it was a no brainer on my choice for the brass! I have done a full prep on the brass I'm running thru the Savage turning the necks and all and have kept the case weights with in 1gn or less, the Varget gives me the best accuracy at this point with the 175gn SMK's sub [EMAIL="moa@200yds"]moa@200yds[/EMAIL]! I have a few more tests to run on my powder charge I'm at 38gn's of Varget and my next loads will be 38.5gn's of Varget to see if I get my max load target velocity which is 2440fps which according to Steven Ragwells book on loading military cases, the 7.62nato brass in commercial rifles this should keep my pressures around 50,000psi so its safe to shoot in any rifle chambered in 308win or 7.62nato, gun) [/QUOTE]
