3 inch kicks like a drunk mule too!The above is great info.
But if u want some real hand slippage. Get your hands on some magnum 3-1/2" shells.
Those are some ass kicking rounds.
Now, don't be a warrior and try to show off cuz u will definitely feel it the next day.
I Will only shoot about 5 to 10 spread out over my range time.
On a serious note, if you want the recoil minimized, a limbsaver pad and some low recoil rounds will do the trick and u will be able to hold that mossy pretty good.
But the 12 pellet 00 buckshot is brutally devastating.
