I used zigzags for my Walker. Used an old bolt I had in the garage.
First, rolled the paper with just the ball at one end then inserted bolt and continued as if rolling a cig.
Did make sure bolt diameter was less than ball. Added 30gr pyrodex,
twisted the hell out of powder end.
Bit the tail before placing into cylinder. rammed the HELL out of the ball and I got what I believe was a faster ignition. It's very time consuming but fun when time permits.
