I'm still trying to decide on a powder for loading my 7mm STW.My rifle is a Remington Mod.700 with a 26" heavy barrel.I plan on shooting 140 to 150 grain bullets and would like to achive velocities around 3400fps.Right now I've narrowed my choices between Reloader 22 @(74.0-79.0grs.),IMR-7828 @ (76.0-80.0grs.) and H-1000 @ (77.0-82.0grs).Would like some input from others who load the same.

Retumbo and RL25, but you certainly cannot go wrong with any of the powders you use.
