[QUOTE="Lefty7mmstw, post: 1117714, member: 48043"] ever do any brisance testing for primers??? I have and the 250 was the only one to literally throw chunks of crap on the catch paper. The win lr and fed lr primers we tried failed to leave anything but a bit of smoke and the rem lr wasn't far behind. The reason we were looking at primers is we didn't want to fire the primer past the end of the barrel on out 30-30 contenders. The sad part was every primer we tried fired the flame out of an empty case beyond the end of the barrel. As to headspace on a belted, it is controlled by the belt. I had my last chamber cut to sub 5 thou headspace for a bit of room as it is a hunting round. When I set my barrel back in 800 rounds I will opt for sub 3 thou headspace to lessen the growth a bit as she is still growing 5 to 7 thou a firing. I want 3 to 5 thou growth in my 7stw with full house loads. [/QUOTE]
