From reading countless posts by Omega shooters, some claim excellent results with Triple Se7en 2f and others complain about such terribile crud rings, that they stopped using the powder. I think a lot of that has to do with where you live, the kind of humidity and temperatures you encounter, and other factors such as gun care. Based on your rifle, it would be a a trial and error type experience for the first pound.

Depending on the size of the projectiles you shoot, have you ever shot Pinnacle 3f or APP. I shoot a Black Diamond XR (same barrel different ignition system basically) and the rifle really likes Pinnacle with 240 grain XTPs as does my Wolverine and Disc. Also there is no swabbing with pinnacle and clean up is a brease.
