Paper patched bullets?
Are we speaking of round balls or conicals? or perhaps a jacketed bullet of slightly less diameter with the paper acting as a sabot?
I've got a TC Impact with something like a 1:28 twist rate.
You all are correct about the prices - I haven't tried any Powerbelts because Walmart had them for something in the neighborhood of $20-ish for 10. How about I take a lead ball and just patch it with a dollar bill to make it seem more effective...
