What do you guy's think is the least amount of powder that you could use in a .50 cal inline and have it still be effective for whitetails? I'm hoping to take my younger brother who's 9 yo out for youth gun season this year but he's not up to the size and recoil of a shotgun. My normal load is 110 grains of pyrodex which is not bad for recoil but I imagine it's different when you only weigh 60 lbs. I'd figure to keep him limited to close in shots, basically bow range, 30, maybe up to 50 yards or so depending on how he does when we target shoot. For those not aware, OH does not allow use of rifles so it's shotgun or muzzleloader only.
