i've been looking for a double barrel 10 ga for a long time, i use a ithaca mag 10, i use to hunt with a 410 and have lost a few, but i do like a 20 gauge
i have a thompson center 36 cal never been fired, i had one long ago shooting squirrels and hogs,,sold it and wish i never did, came across one 2 years ago mint condition,,and never hunted with it,,lol
i have one that shoots great using round balls, i make my own,,i use pistol powder 60 grains and i can tack them at 40 yards, it is a great gun to shoot
if your ball is stuck at the bottom of the barrel, remove the nipple stuff powder in the hole put the nipple back, put a cap on and fire it,,the ball will come out easy,,but make sure the ball is all the way down the barrel
