I thought about loading those speer TNT's for my .308 but i'm not sure what kind of accuracy to expect with a 125 gr bullet in a barrel with a 1 in 10 twist. Is a 1 in 10 twist to fast for that light of a bullet?? Ive also heard that light bullets arent good for fast rifling, is there any truth to that?? I have also heard of fast rifling with light bullets can also cause jacket seperation in mid flight, would i have to worry about that with my 1 in 10 twist??
