Checking FFg/Pyrodex Spout Volume:
Hey guys,
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???? Thanks!!!!! |

You can measure real bp by weight. Everything else is by volume. I use 25 grains in my .36's. Most people use 20.

The conical may or may not allow 20 grs under it. I usually shoot 15 grs for the conical and 20 fro the RB. I use a lube wad for the RB but not the conical.
LEE makes a nice double cavity aluminum mold for the .380 ball and the 130gr conical. If you want to go volume you can get a 0000 buckshot (.380" dia.) mold for about $40 that casts 10 balls per pour (no sprue cutter, balls are not perfect spheres [there is an "equatorial" flat area of about 1mm where the mold haves join] but very serviceable ammo) from buckshotmold.com. Or you can go delux and get a biglube.com mold that will throw 6 very precise .380" RBs per cast.

Hawg,
The Pyro-P is so spongy that I wouldn't be surprised if you could fill the whole chamber and still ram a ball (no wad) down enough to clear the mouth. It makes a pretty stout load.

You can find charts of case capacities in H2O with an internet search. .357 Magnum measures about 27 grains. .30-30 measures about 45 grains. |

There is a list of brass cartridge measurement some place. I've seen one quite some time ago. Measurement used was grains I believe. Brass cartridges case's were nothing more than different size quick Chargers. Someone here had that list available as I recall.
