Ive always been a 12 gauge and wanted to have the most power i could get . 3.5 inch ... heck i would shoot a 4'' if they made them.
But now days im finding out I like my teeth not rattled out of my head.
I got a 20ga 870 and after some messing around with ammo choke combos ill never go back to the 12s
I recommend the weatherby 20 ga.
