I've heard that the slow 1:38 twist in 44 Mag and older 444's doesn't perform well with heavy bullets. Does anyone have experience with this? What kind of accuracy can be expected from these rifles? I keep thinking abouting getting one, but I am concerned that I would be disappointed in the accuracy. Any input? (My only comparison would be a 444 that I had years ago. The heaviest bullet I tried was 265gr but it would shoot them into a little more than a inch) Thanks!!
