The 250gr .452 is the one I will try first as when I looked it up it is designed for a velocity that is what I am shooting with SW I am hoping since the main difference is in the interlock and a thinner jacket on the nose than the newer SW that it will shoot accurate at max loads as the ones used in the 450 Bushmaster which they are designed for opened in an ideal shape.
The 325 if I remember is a 458 rifle bullet, was it designed for the 45:70? Lee
