SDB - Powder Charge Accuracy
Quote from Reloader on January 12, 2010, 8:52 amI've been looking to upgrade to a progressive from a single stage... how accurate is the powder charge with each drop on the SDB?

Quote from Reloader on January 12, 2010, 3:33 pmWith most ball/spherical powders and small flake powders, expect charges to stay within +/- .1 grain, which is as accurate as your scale is. For large grain flake powders such as Unique, 800-X,etc, expect variations to remain within +/- .2 grain.

Quote from Reloader on June 28, 2010, 5:18 pmI am reloading 9mm luger and .45 ACP using SDB press. With 9 mm the powder charge is very accurate (less than 0.1 grain variation). But when I switch to .45 it is not so consistent, variation goes up 2-3 times and it makes a big difference on the bullet speed - more than 100 fps (and I need a constant power factor for IPSC).
I use the same powder for both (Vectan BA9 from Nobelsport), the same powder measure, I only change toolhead with dies and shellplate and adjust the powder charge.
The powder charges are not so different, 4.2 grains for 9mm and 5.6 for .45ACP.Any ideas about these differencies in .45ACP powder charges?!?
