I keep a case next to the pan with its weight written on it. I also periodically check random cases on the block and when I'm done with a run I again check 4-5 random loads.
The hardest thing with this setup is finding an easy way to transfer powder from the scale pan to the case. I have several different funnel setups and for my compressed loads I must reach up over my head to dump the powder, tiring.
Pete,
I watched the videos on 6MM BR.com and another video I think on the RCBS site. Unless they're slow I can beat them handily, 30% at least.
I too throw and trickle with my fingers. I've learned to seed from 1 to 5-6 kernels perty handily and can nail the weight to the kernel 50% of the time.
Taking kernels out is the slowest, I've used several little plastic tweezers and scoops but the quickest way yet is with my latest plastic RCBS funnel/tray I can pinch up 2-3-4-5 grains and drop back in the remainder.
I DO want to try the Chargemaster but I've talked myself out of it so far
BTW, I've seen the Chargemaster advertised as "accurate to the tenth of a grain"...... Is this "plus-or-minus" or a tenth total? anyone care to share? Using H4350 this translates to either 5 or 10 kernels accuracy as a kernel of H4350 normally reads as .02gr.
