[QUOTE="Lefty7mmstw, post: 753033, member: 48043"] It seems some loads in the 270 wsm are flakey with rl19; my dad had that trouble years ago with his 270 wsm and even other powders didn't really cure its ills. He eventually traded the rifle. My 300 win varies less than 60 fps real world with rl22 and 165's, and is a solid 1/2 moa rifle at any temp. with it. Same story with my 300 rum and rl25 and rl50. Can't say for sure yet on rl33 but it looks promising. I think it's often a load right on the edge of being ballistically stable, ie. a bit cold or hot on the primer or a bit cold or hot on the pressures that kills the rl powders at times. At one temp. it's fine but you swing a bit and it gets buggy; I've seen it with 7828 and 140's in the 7rem too. At 60 f or warmer my 7rem loves 7828, but you cool down much and it goes from a 1/2 moa load to a 2 moa load. You have to prove your load in real world conditions and not hang your hat on a slogan.
