I have used that Ranchdog bullet on exactly one big game animal so take this for what it's worth. The shot was maybe 60 yards away at a slightly quartering away decent sized white tail buck. Bullet hit between the last couple of ribs on the near side and exited low forward of the shoulder on the far side (I was in a tree stand so downward angle) how it missed heart, I don't know, but it did. The deer died pretty quick, but both entry and exit wounds were small and didn't leave any blood on the ground. The bullet was cast of 50/50 COWW to pure with 2% tin added, sized to .311, lubed with LLA and pushed from a .308 with 28 grains of IMR4895 and a tuft of dacron on top, never checked, but guessing 1800 FPS.
So that bullet, cast softer than you plan to and moving slower had zero penetration issues going through almost three feet of deer (granted, no real bones hit) but did show signs of expansion problems. I'm told hogs are tougher than deer, but if it were me, I'd soften the alloy and slow it down if need be.
