Pyrodex loads in manuals: Grains vol. or grains wt.??
Checking out the loads in the manuals that came with my '58 Rem., I see that the max load recommended for Pyrodex P is 28 gr. while for fffg Black it is 35 gr.
I use Pyrodex in my front-stuffers and have always understood that Pyrodex and Black are exactly equivalvent when loaded BY VOLUME. IOW if 35 gr. of black is OK, then 35 gr. of Pyrodex should be too, if loaded BY VOLUME.
However, Pyrodex weighs less than an equivalent volume of Black. Even if a measure set to 35 grains is filled with Pyrodex, it will weigh approximately 25% less than 35 grains.
I normally load by volume (using a measure# and not weight. Must my volume measure be set at #or below) the lower limit for Pyrodex listed in the manual?
Being an engineer, I obsess about these things...forgive me.
