The RCBS measure with the micrometer adjustment option has been a good measure for me, but I'd recommend looking at something else. If I were buying another measure it would be one of similar good quality, and with a micrometer measure for repeatability, but also one with feature that lets me drop my powder out quickly after a loading session. I have also had problems with some powders in the RCBS due to what you might call "static cling". Bullseye is one such powder. I just can't get very uniform charges with it. The same powder in a Dillon measure gives excellent uniformity. I have also had problems with some short stick powders in the RCBS. I believe H4831-SC, as is Varget. The symptom I've experienced has been that the sticks bunch up in the drop tube and a partial charge is dropped into one case, followed by an excessive charge in the next case.
If you get one, I recommend also getting a stand for the measure. I built one myself, but having a good stand is a good accessory. It's not necessary, but makes the work more enjoyable.
Whatever you get, buy a quality tool. This is one tool that affects the safety of your charges and buying an inferior model just to save a few bucks is a bad idea.
I'm interested in seeing responses from others on this subject because I'd like to replace my RCBS with something better.
