[QUOTE="diriel, post: 527282, member: 26983"] @ darr, 4.5" for a single 10 round string out of TEN 10 round strings, 100 rounds down range total. Which is actually pretty decent for ammo that is cranked out in mass. "" 3.6.4.1 300 yard accuracy. (M109) [The extreme spread of any individual 10-shot group shall not exceed 4.5 inches at 300 yards. The average extreme spread of ten, 10-shot groups shall not exceed 3.5 inches at 300 yards.] '' The thing about the 71k pressure is.... A LOT of Magnum reloaders hit that pressure range quite commonly. They just do not realize it. The max pressure they list as allowable is actually not to exceed 78k psi... just ouch! Have a good one, Gary [/QUOTE]
