The only charges I weigh are those being used in long range competition. [1000 yd] Life is too short to be spending time trickling up every charge to exact weight, since out to 400 yards, the difference .2 grains of powder makes in any hunting cartridge cannot be seen. I use the scale to set my measure, and recheck every 30 rounds or so, look inside the cases with a decent light before seating bullets, assemble the ammo, and shoot away!! Comments that have been made about variances in brass are valid. Different makes of brass can be a lot different in weight. EG. My 8x57 mauser brass varies 35 grains from lightest brass to the heaviest. Have to watch that, since a blown primer can be the result of dropping a charge developed in a lighter case into a case with a lot less capacity. Regards, Eagleye.
