In my opinion both work good. When i hog hunt with a shotgun i put remington 2 and 3/4 inch slug in to be fired first and buckshot 2 be fired second. That way if u hit them with the slug and he charges u r shootin the buckshot and have a better chance of hittin and killin the hog b4 he hits u.
her in texas we have lots of pigs i cant count how many we have killed lol.
Well anyways i use 3 1/2 12 gage Ultra Mags Im not sure that what the name is but well i droped 4 pigs with them any were from 40 yards.. it will nock chunks out lol
