[QUOTE="Pdvdh, post: 1312041, member: 4191"] Pull some bullets and measure the precision of the Hornady factory ammo powder charges. See if Hornady weighs their powder charges to 0.02 grains. It's a virtual certainty that their cases are powder charged volumetrically, and that I'd be able to detect powder charge differences exceeding 0.1 grain on both my Chargemaster, and my 45yr old Ohaus balance beam scale. I'm unaware of any major ammo manufacturers weighing out individual powder charges. Everything I've read is that they dispense powder charges volumetrically, and common tolerance exceeds +/- 0.1 grain. And yet you consistently record SD at less than 10fps... [/QUOTE]
