725,
EXACTLY.= My favorite "hog gun" is my old Model 760 Remington in .300 Savage.
(My GCCB load is a "SA War era" equivalent of the old-school .30-40 Krag load.)
Imo, any bullet that will consistently "pass through" a hog's chest is likely adequate. = Hogs are not "bullet-proof", though some huge boars sometimes seem to be!!!
yours, tex
