I weigh all of my powder charges (for both rifle and pistol shooting) with a Lyman Electronic Scale, for precision shooting with both.

With the original formula Herco powder, I haven't noticed a great deal of dirtiness with the 9mm Parabellum; whereas, Unique has always been a filthy burner for me, both in its new and older formulas.

Respectfully, Sieger

I've settled on CFE Pistol Powder for .30 Luger, 7.63 Mauser, 7.62 Tokarev, 9mm. .40 S&W and .45ACP. It's has a burn rate slightly slower than Unique according to the burn chart and is very clean. I meter it through a powder measure and my loads are very consistent. I weigh every 10th round and am never off more than .1 grains.

Most electronic scales - yours included - are accurate to within .1 grains plus or minus. That's the same accuracy I get from my measure.

For precision rifle loads, I use an A&D EJ-123 scale that is accurate to within 2/100 of a grain. I run my loads off on an RCBS Chargemaster and then fine tune them on the A&D scale.

I go for accuracy and function. I NEVER push my loads to the max. I've never seen the need to do so.
