90 grains of powder in a 50 cal pistol

Didn't look like a pistol to me. Am i missing something?

I usually stick to about 30 grains or less on my sidelock pistol; anything more will just make a bigger flash & smoke in that short barrel. I don't honestly know what the safe max level is & don't want to find out empirically.

that didnt look like 90 to me. my bp rifle with 90 makes a bigger smoke screen. unless most of it is just shooting out the front unburned

90 grains of black powder is excessive for a .50 cal muzzleloader. It is not going to burn in the barrel- it burns outside- after being blown out the muzzle. Rough rule of thumb used to be 1/2 to 3/4 of the bore diameter for a pistol, and 1 to 1.25 the bore for a rifle.

Not sure of that rule of thumb...

I'd always learned and taught "always less than the bore in grains of black powder in a pistol." Long guns are tougher.

To put 100 grains in a .75 Bess is fine. Was more than that in battlefield use. The same load could've been used in a .58 3-band or maybe even a .50 cal rifle. For bigger-bore guns I do try to stick to the bore in inches with equal grains of BP and always less than twice the bore as the bore gets smaller (a .45 rifle would always get less than 90 grains for example -- MAYBE up to 85 then) which is a rule that should govern all longuns in any case IMO. Still, the bigger the bore the closer to 1:1 grains of powder to bore in inches, and the smaller the bore the closer to 2:1 grains of powder to the bore in inches.

You can`t get to much powder in a pistol like that, it will just blow it out & not build up any pressure.
