Ok a quick question, I have noticed that with fine powders, like h110 my powder measure will throw a charge within 1/10th of a grain of what I want. No biggie with my pistols at all. But with a larger stick powder like IMR 4831 it throws a charge within a half a grain. I'm not working with top end loads, is the half a grain variation really that big a deal? My OCD has been making me weigh and trickle a exact load for my gun, but does it really matter????
