I got to spend some time using my newest addition to the reloading bench. This weekend I used my RCBS Chargemaster for the first time.
My press is a progressive, Dillon XL 650. I normally just use my powder measure that came with the press, but I was developing some new loads and decided it would be an excellent opportunity to test out the Chargemaster.
Using it was much easier than my Dillon powder measure for load development. Accuracy/ consistency was as expected, nearly perfect. The RCBS has a tolerance of +/- .1 gr. My dillon will meter powder consistently enough for my needs, but it takes a while to adjust the powder measure properly when making slight changes for load development when doing accuracy testing of new builds/barrels.
I have several RCBS tools for reloading. They are all time saving devices that greatly enhance my ability to increase volume with no loss in consistency, some with an increase in consistency over whatever it was meant to supplement or replace.
Next addition to the reloading bench will be an automatic case feeder for the press. Ive been feeding them by hand and feel like now that I have what I have this is going to be the most helpful area to focus on next.
Many people say progressive presses dont provide for enough consistency to produce accurate loads. I use mostly Ramsho TAC when loading .223. My favorite load is 23.4 gr with a 77gr SMK. Ive shot sub ¼" groups at 100 yards while laying prone unsupported using that load produced on my Dillon XL 650. I frequently dispense powder into 20 cases and measure them all to check for variation. normally less than two of them show any measureable variation on my scale. The ones that do vary display less than .2 gr of variation from the others. I dont see some go low and others go high on the powder charges. When they do vary, the ones that vary consistently go slightly low. For what I am capable of doing and what I intend on doing, I have never experienced a problem caused by the ammunition produced on my press. If I really want to, I can use the chargemaster to dispense and measure each powder charge for me to increase consistency a little bit.
