if you don't want to discourage your son or grandson with a complicated muzzleloader ,give them something simple to load and clean ..a break-open is hard to beat for a starter ,also very save less moving parts ,easy to clean ,i always say keep it simple and functionel ,once he is hoked on blackpowder hunting he can always get a flintlock ,loose powder ,and measure up his own loads ,if that is whatHE wants ..ex. the other day i was hunting with my friends and one of them had a KNIGHT the old model bolt action ,with the red inserts ,way too complicated for my grandson ..
