So apparently the "standard" load for both of these was 28 grains of "pistol powder" under a 450-grain hollow-base bullet... in some pinfire loads the charge was even smaller.
So, just out of sheer curiosity...
What kind of velocities do you think these would have?
I've read one source that claims 725 fps, but that seems suspiciously high to me, given only 28 grains of black powder with such a heavy bullet!
I've also seen someone who actually loaded for one, they posted that 42.5 grains of Goex FFFg under a 457-grain bullet gave them 680 fps.
So... 28 grains of "pistol powder"... maybe 600 - 625 fps? Or even lower? What do you think?
