I'm sure some one here has "Been there, done that" I'm trying to find a powder that will <UL TYPE=SQUARE><LI>Fill a 7 MM Remington Magnum case to the shoulder. <LI>Push a 162 grain AMax bullet at 3000+ FPS out of a 26" barrel. <LI>Preferably not a temperature sensitive powder[/list] I've been playing with some RL25 this morning. It doesn't quite fill the case as full as I'd like it, but it is pushing the bullet out at a 3126 Ave speed. Right now, I'm just playing with the seating depth. But the last two three shot groups have had 2 holes nearly touching, and the third hole several inches high. ( 300 yards ) The thermometer said 82 degrees as I came in to write this. Is it already getting to warm to use this powder? Or could something else be causing me the flyers?
