Well, the thing is that buckshot won't expand where your .45-70 bullet does. Back in the mid '90s I had occasion to put down over 70 hogs, a couple of yotes and a few other assorted critters with buckshot. Mostly used #3 buck in a 20 ga but also used other gauges and shot sizes. Smaller buck is a quicker killer than large is the distilled message. Thinking it occurs because the number of wounds are higher.
I seldom shot anything beyond 30 yards and think folks shooting out beyond 40-50 yards are sprayin' and prayin'. My comments about buck penetrating thru and thru was not BS, just reporting the facts. Note too that I qualified that by saying it wouldn't happen if bone was struck.
BTW, a load of #8 birdshot at 20' will kill a hog deader'n a stump right where it stands.
