My 7mm Magnum Weatherby shoots Barnes bullets very well. Thus far I have tried 140s, 150s, 160, and 175s and all shoot very well. My rifle has an aftermarket barrel (don't know what brand) with a 1 in 9" twist. My favorite powder is RL-19. RL-22 works well with the 175s. For some odd reason cup-and-core bullets aren't accurate in this rifle.
