a-t-g, you can start out w/ M1 carbine or the equivilant casings, .30 cal I think, just glued on the un tappered end of your dowel. If you need more weight, add a little molten lead, let cool and glue on. You can use the same casings and nock the primer out and find a nail that will fit in the hole and shorten and sharpen that for a more pointy tip. Did you check out the small game sticky up @ the top of the page? dpgratz
