I have the RCBS Uniflow Powder Measure that came with the RCBS master kit. Put my first few rounds together last night and found that the metering required constant fiddling. I followed the instructions carefully, dissasembled and cleaned all the oil/rust preventative out of the workings then ran a bunch of powder through at max setting before first use. In the instructions there is mention of an optional small measuring screw assembly, would that aid in getting consistent powder throws with the small amounts needed when reloading .40 S&W pistol rounds?
I loaded just a few testing rounds using once fired Winchester brass, CCI #500 SPP, 180gr Berry's RS and Hodgdon Longshot powder. Did 10 each using the 6.5gr starting charge listed in Hodgdon's loading data 6.7,6.9,7.1,7.3 I ended up weighing almost every other charge. The charges were not off by alot but would be just slightly above or below the zero mark on my RCBS scale(less than .1gr either way) Is that just the nature of the equipment that needs time to wear in or type of powder( tiny flakes ) that was causing this? I tried my best to operate the handle smoothly and consistent and I guess I was expecting dead-on measurements every time. Do some brands of powder measure out better than others?
Thanks
