I see that a few of you guys (rubberhead comes to mind) on here shoot some real nice older double barrel shotguns, I was just wounderin' what type shells you were using in your guns. Bismuth, the new "classic doubles", or something else? I have 1952 savage/fox model B 20ga and would like to take a few woodies with her this year, I know she ain't a real AH Fox but it's in good shape and l like shooting it so I don't want to mess up the barrels. Thanks for any input.
