[QUOTE="backwoods83, post: 851972, member: 29890"] 1st example, use CCi 400s in a 22 hornet, run it up until you see pressure signs, now you have just destroied your 22 hornet brass, this works both ways, not all brass is equal nor is the cup thickness on primers, or the size of primers, one could feel loose upon seating and another brand snug, .001-.0015 makes a big difference in how primers fit. No I'm not suggesting to run 10k psi over saami spec, but I'm also saying that multiple near max (58k on a 60k psi cartridge) loads can cause pockets to loosen, doesn't mean the brass is bad. The 338lapua is another good example, in saami terms its psi max is 65k, in cip terms its 68.65k, yet we still use it on actions that have been chambered for rounds as small *** a 222 (remington 700) they are available in some european countries, so do you think most europeans are going to run them around 64k or 68k?
