Yes Sam use some sort of blunts, although I guess a broadhead would work. Judos, or hex heads, or a blunt that has been drilled to imitate a hex head's concave face all make great stump shooting tips. They do not bury too deeply into anything (unlike a broadhead), they are less prone to burying under grass, specially the judos and they are not prohibitively expensive.
One you get bored with just good shots, then get creative and shoot from behind stuff, below stuff, over stuff, thru stuff, and then, when you get really cocky... Bounce it off this tree and into that target !
The best part is you can shoot a zillion times a day if you wish, unlike most hunting situations.
