RE: How much powder to use?
Take that material, cut into strips about an inch and a quarter wide and maybe 18 - 24 inches long...
Take a putty knife and smear SnoSeal on one side, put in the microwave about 15 seconds with a few paper towels under to absorb the excess lube...Then put in a zip lockbad and label...Do the same with
other lubes you might want to try...This way when you get to the range you can see which works best for your gun...Just center the ball, push down flush with the muzzle and cut with a sharp knife, and ram her home...
