[QUOTE="Lefty7mmstw, post: 834591, member: 48043"] My brother has been shooting 280's since he got out of diapers it seems and he's always at/over 3K fps with a 140 in a 22" pipe and usually nipping at 3050 fps. He's using rl22 in a remmy with a 140 ct on top at present. Top load for rl22 in the 2005 Alliant data for the 139 hornady is 59.5 rl22 at 3000 at 57.5 kpsi peak with a rem primer and remmy brass. I've seen him make some shots with that cal. that I likely wouldn't attempt and I'm a showoff behind a rifle. ps. listen to 375fan on the chrono; you are likely either seeing the powder blast or getting double shadows from the sun angle if it's a low sun angle.
