I know that 2fg is considered rifle powder and 3fg is usually described as pistol powder but does it really make much difference?
The local supplier had only 3f Goex available so I using it in my T/C New Englander with round ball. I am using modest charges of about 70 grains on the measure and accuracy seems pretty good so far. I'll be getting some Swiss or Graf next time and I want to get enough to make up for the Hazmat fee. So as not to waste too much money, would it be better to stick with the 3f or get the coarser 2f?
