M7 Stainless Remington in .308 loaded with a 140 Barnes to about 2850 fps will stop any hog in Texas.
I have this SKS, though, that I've set up to night hunt and am about to get more into that before the hot weather and mosquitos come.
I really need to work up a hunting handload for it, though, as the bullet I was using got discontinued. I'm going to buy some light weight Barnes .308" bullets to play with. The main reason I stuck a lighted reticule scope and scope mounted spot light on it is that I really had no good use for it other than a range gun. LOL! I don't know if it's the optimum hog gun, but I figure inside 100 yards at night it should do okay. I don't like shooting big hogs, anyway.
Daylight, I'll take my little M7, light, handy size short action and .308 is PLENTY to any range inside 400 yards, though most hogs are taken well inside 100. I KNOW it'll work, though, cause it ain't failed yet in 10 years I've been hunting with it, both hogs and deer. You can keep your pistol caliber carbines. .308 is the real deal.
I get 3/4 to 1.0 MOA accuracy, too. Ain't fired a lever gun yet that can match that, though a BLR can come close.
