In all honesty, I've never put a round through this gun. I bought it at a pawn shop, it is in good shape on the outside, I had a guy at Kesselrings look at the throat with his fiber optic deal and he said it showed no wear. I have shot a different gun very similar to this one and it shot a whole box of cheap remmington ammo through a hole about 5/8 to 3/4 inch. I have been thinking of taking it down to Kenmore to find out for sure what it will do but I haven't got around to it. When I do I will post results.
