For me it changes with the projectile more than with the rifle but that also changes from one to another. This is the way it goes with my omega
goex or swiss-lead bullets with out sabots
Prodex- heavy loads with lead bullets or sabots
Gold- light loads for light bullets in sabots
App- Best for clean accurate loads with all Shock Waves[ under and inch @100yd if I dont screw it up[FF]
Pinnicale so far so good have not finished testing yet.
777 makes it necessary to clean every shot; about the same velocity as APP almost as Acurrate as APP if you clean good every shot.
