Today I got a pound of Swiss to use instead of Goex for cartridge loading. So when I get home from work, I empty the Goex out of my Lee Perfect Powder Measure and re-fill it with the Swiss 3f. I dropped a few charges without weighing them and just dumped them back in the hopper to make sure everthing was settled.
Since the last thing I loaded was 45LC the scale and powder measure were already set to 40gr. So I dropped another charge and stuck it on the scale and much to my surprise it weighed out considerably heavier than the Goex. 11.5% as a matter of fact. With the powder measure throwing exactly 40gr of Goex, she threw 44.7gr of Swiss.
Now I've read for some time that Swiss is approximately 10-15 percent "hotter" than Goex. Might we make the assumption that it isn't really "hotter", just "heavier"? Meaning that by using volumetric measurements you are actually getting 11.5% more powder in weight when using the same volume, therefore the hotter is just a way of stating that you are actually using more powder if you are measuring by volume??
Anyway, I only had time to drop two loads into brass before I was informed dinner was done but noted that the level in the brass using Swiss is considerably lower with 40gr weighed than the Goex. I'll gonna load about a dozen with the 40gr then cut back to 35gr and we'll see what kind of difference we get.
