Checking FFg/Pyrodex Spout Volume:
I found my 10 year old powder flask (and was used when I got it) and IIRC, we cut down a .44 caliber spout for a .36 caliber 'twister' derringer I had as a kid.
I want to use this old flask with my new Pietta .36 Colt, but I seem to recall you do not want to measure FFg or Pyrodex by weight, only by volume.
Does anyone have a quick, reliable method for checking this????
Like perhaps a 9mm Luger case level full would equal 'X' number of grains volume???
Also, what charges should I be shooting for under both a .375" ball and conical in the Pietta .36 steel framed revolver????
