[QUOTE="JeffVN, post: 1499385, member: 2261"] +1 to what Milepost said about the RUAG 416 Barrett brass. The crimped & primed version of that brass (I cut out the crimp by hand on a lathe) needs to be fired 2X at low pressures to work harden the rear end of the brass, at which time it is ok for running in the 50,000+ PSI range. If you just load it and shoot it at higher pressures you'll open the primer pockets at least 0.001 or 0.002 and up to 0.004 with each pull of the trigger. (go ahead ask me how I know) Can't talk about the unprimed and un-crimped RUAG 416 Barrett brass as I've not loaded any of it yet (sitting on 200 pieces). Having said that, the brass is pretty consistent on case volume based upon fire forming velocities, but you should plan on cleaning the necks (turning) if you want low single digit ES & SDs. The RUAG has neck thickness variance of up to 2 or 3 thou between cases (better than the standard Barrett which had neck thickness swings of up to 4 thou on the same case.) Jeffvn [/QUOTE]
