Volume vs. weighing in grains - Page 2

Take a powder measure.....set it at 60 grains.
Now...here's the hard part....get four brands of FFg BP...say Goex, Swiss, Elephant, Graf. Pour and weigh each of those 60 grain volumes.....they will not weigh the same. There may be as much as a 10% difference.

Weigh out a true sixty grains of those four brands of FFg black powder and every one will be a safe load in a .58 caliber rifled musket.
Weigh out 80 grains of each one of those and every one will be a safe load in a 12 gauge shotgun.
No, they won't have identical velocities but you won't blow up your gun.

Now weigh out 80 grains of Pyrodex or 777 and load it into a 12 gauge and I don't want to be the one to shoot it.
