Karl - I tried all granulations of GOEX in my .50 3-1/4" Sharps with from 140gr. of 2F and 3F and up to 170gr. 1F Meteor. The Meteor 1F powder was very dense and heavy, hense the weight.

2F gave the best accuracy and velocity, with 3F flowing the primer back around the firing pin, demonstrably showing pressure levels too high for this particular action. The Sharps has a large angled firing pin, which, due to it's shape and angle, leaves room for primer flow with hot loads.

I successfully loaded smokeless in this round without pressure problems, to elevated velcotiies way over black powder, did this with very much lower pressure than the 3F charges gave.

I would not use 3F in any make of BP in anything but the shorter cases, such as the .45/70 or .45/60, or shorter yet.
