    I believe it. I have pulled my cases from rotation after 6 loadings, but only due to Perry paranoia. I bet I'd get another 6 out of them. I also leave my light coat of lube on. It is easier with the Dillon and I have found no detrimental results. Call me what you will but I have many thousands of rounds downrange using a system much like "Slamfire" outlined and I've had no safety concerns or malfunctions. I DO clean my chamber very well between most matches just in case. I am using Midway spray on lube right now. I use a Bartlesman (upgrade from a Gracey) and a Giraud trimmer. Also I'm using a Redding S Type bushing die with the bushing that has the neck barely touching the expander on the way out...acting as a sweep more than anything. All the necks from RVOW are inconsistent so I trim when I take them out of the box. I am trimming just a hair short of "minimum" and have noticed a small change after the first firing. After that they stay very consistent and don't need another trim before I toss them.

    I use LC 90 brass for my match M1A. I pay very close attention to FL sizing, using a case guage, to make sure they`re sized within spec. I use modest loads, (40.5-41 IMR4895 under 168 SMK), and I only get 2-3 loadings, after once fired, before I start getting head seps. Why? Im tempted to size less, but I dont want the risk of firing with the bolt out of battery. I just bought a Redding S-style NK bushing die, and body die, just to help concentricity, will this help? Thanx-

    I would try to use a Stoney Point headspace gauge on my fired brass and just bump the shoulder back with that S die about .002-.003" total and try it informally. Make sure it son't slamfire (shouldn't) and keep your chamber clean. Oughtta work and increase your case life some.

    Steve, I have a RCBS headspace guage, (the micrometer screw-down type), will this work ok? Ive taken cases that were fired in that rifle with the gas system off, (so it can conform to the chamber more completely, before being extracted), and the expanded cases were alot longer than my sized ones. Also, they arent very consistant in measurements. I know the headspace is within specs, but maybe close to being a little long. I had a good `smith build the rifle a few years ago, (John Holliger), with a Douglas match barrel, and I doubt he reamed the chamber incorrectly. Any help would be appreciated. Thanx-
