I Shoot the barnes 3" Expander in mine. Did a couple tests with a 1/2 dozen slugs and the Barnes was best (which is good cause I like them best). Had it for a year now. Took it out last weekend and tested it out to 200 yards. Its "hunting accurate" out to 200 yards from the BENCH. I'd be happy to put it up against any of the guns people around her hunt with for slug hunting deer.
All in all, slug guns SUCK for deer hunting. But its what we have. I'm strongly considering going back to the smoke pole for whitetail in Iowa.
But if I have to shoot a slug gun, it will be the savage 220.
