I have two .44 mags that I hunt with, one scoped, one not. The 300-gr Federal CastCores are the most accurate loads I have ever fired out of these two guns. I wouldn't go hunting without 'em. Now the 180-gr .357s are a different story. Didn't get the same results out of my 6" .357, but since I hunt with the .44s and a .41 now, I haven't really worried about it. But again, I sure do love those 300-gr .44s!
