1:7 twist like them heavy bullets. But yes, load development for your gun if you reload. 1:9 shoots 55gr and less.
It really boils down to the distance you want to shoot. Heavier bullets will hold up better the farther out you go.
So if I want a rifle that will shoot some distance, say 400+ yards and I use a 1:7 barrel, will it still be okay for closer(<100 yards) stuff with a lighter weight bullet?
