<p>[QUOTE="AWJ, post: 3122124, member: 96434"]The powder charge specified in the contract calls for 328 grains of powder (the weight of the .62 caliber ball) PLUS the 26 grains (half the weight of a Real) = 384 total grains of black powder. This is a huge, excessive powder charge with modern gunpowder. The powder back then must have been much, much weaker. I'm still researching the powder formulation.[/QUOTE]</p><p><br /></p>
