Getting low on wads, I hit the local cloth/arts and crafts store. I found they had some wool felt that was almost 1/8 thick. I purchased a half a yard of the stuff, which I then stiffened with a cornstarch dip.
I drilled out a .45 acp case I had to run a bolt through the primer pocket, screwed it in and chucked it up in the drill press. A bit of sharpening on the case mouth with a fine file and it is off to the races. Total cost about $5.00 for the cloth and cornstarch. Probably enough materials of a thousand (i.e lifetime supply) of wads.
