You could also consider a traditional style rifle and shoot round balls. Well over 30 whitetails in the past 16 years fell to my .50 cal Lyman Deerstalker firing a round ball. They are cheap to shoot and a lot of fun.
open iron sights, external hammer and real black Powder. Best way to go. there's no seperate BP season any more so go traditional. your friends will thank you for it.
