If I get the Mossy 930 12ga. in blue and walnut I got my heart set on, I may try some of them fancy K.O.'s on deer.ETA - Brent, Brenneke is now making KO slugs in 20 gauge too. You ought to try some on the bigger hogs you have to deal with.
But for hoggin' I am armed only with bulldogs and a pocket knife
To dispatch our catch when ready to butcher, I just pop them in the "brainium" with a .177 pellet from the gamo or use a .22lr...
I have since quit offering to guide folks on gun hunts as the chance of getting on them is too remote. And doing it for free (not a licensed guide), I was investing too much money, blood, sweat and aggravation trying.
When I was doing that, I would always tote the 20 as a backup since I didn't have my sure fire hog seeking missile bulldogs to back us up.
