I'm with burnie, I like to chase em with my bow, but here's what my buddy did with his 12 gauge, using 3.5" 00 buck. I set him up in an area where some hogs had been tearing up the place. He was sittin in a chair in some brush for about 30 minutes, when a group of about 8-10 came out behind him. He's got very bad hearing and didn't know they were there until they were about 5 yards behind him. He turned his head, saw them, and then started lettin em rip. I was about 300 yards away in my climber and thought that WW3 had started. Anyway, he shotfive times. He dropped 4 hogs in 4 shots before the others ran away.His fifth shot was to finish-off one of the 4. I guess what I'm trying to say is that 00 buckshot works pretty darn good, especially if you want some quickfollow-up shots.
