Of course the 12ga. is just as good. If your using this shotgun for deer and deer size game then get the 20ga. top it off with a good scope, on mine I have a Leupold VX-II in 3-9x40, also try a few different brands of sabot slugs, my H&R Ultra Deluxe 20ga. loves the Hornady, also stay with 2-3/4" shells in either the 12 or 20ga. My 20ga. is a tack driver. Good luck !!!
