RE: Another Slug Gun Question???
shoot the 20ga yourself, and see how it shoots. It may do more than your 12ga.
Only reason I shoot a 12ga is because it's what I have....If I had a 20ga to shoot, I more than likely would be shooting it, if groups were as good or better, I'd pick the 20ga. If they weren't I'd have to stick with the 12ga then.
