[QUOTE="Lefty7mmstw, post: 1494588, member: 48043"] it seems a bit odd that someone would advocate staying away from rl powders. I've seen a 7stw with a pressure trace push as hard with rl25 and 140's and at 8kpsi lower pressure than i7828 would do. I use rl15, rl19, rl22, rl25, rl33, and rl50 in handloads and all perform very well. My highest vel. variation is with rl22 with a 165 in my 300win; she is right at 3200 fps in cold weather and she'll creep up to 3270-3280 fps in hot weather. rl33 and rl50 seem to have about zero variation in my 300 rums...
