I'm saving up for a savage 220 20 gauge slug gun. I need advice on scopes and other accessories. Does a 20 gauge slug kick hard enough that I need a scope that can handle slugs or can I put a Simmons 8-point on it? The gun itself weighs 7.5 pounds and most regular 20 gauge shotguns rarely push 7 pounds. Basically; is 3" of eye relief enough? Can the 220 be loaded through the breech or is it exclusively a mag-fed gun? Will savage 110 mounts fit? Thanks guys!
