.257R is a classic and hits well above it's weight class. This group was shot with a Brux (24") barreled LA M-700; this COAL won't fit in a SA. This load whacks WT's and hogs with authority. What's not to like. Check that velocity. No pressure signs at all.

Gun also likes 115 gr. NBT's over H-4350 at around 2,950 fps. That load whack'em and stacks'em, groups just as good or even better.
