Thread: Beams scales vs automatic powder dispencers

I choose fine powders and throw, from a good quality thrower checking about 1 in 50 for accuracy and an eye ball in every case, yeah I go through a lot of eyeballs, but its pretty quick. Even reasonably coarse powders like 2213 , 2209 throw within about .2 of a grain.
I think the other variables in the reloading equation ( case neck tension, bullet seating depth. wind and atmosphere account for more accuracy issues than the variance of +/- .1 grain
Remember that in doing accuracy tests and building up to an accurate load there is usually a sweet spot covered by +/- .3 grains
