I know it may be hard to resist the urge but folks please stay on topic, the intent is not to drift from the question at hand. There is no need to proclaim the precise measuring virtues of some other measure, or recommend something else. I have RCBS Uniflows that I am working with and they have the standard adjusters and are being manually operated.
The Uniflow can be configured in many different ways, left hand, right hand, adjuster to the front or to the rear all with a large (10-110g) or small (0.5-50g) measuring rotor. The generic guidance is small rotor for pistol and large rotor for rifle and the tap-tap on the stroke is the desired stroke. Ball and flake powders generally meter ok, but stick powders do not. The baffle is usually recommended to keep a consistent head pressure on the powder just to get those out of the way. By intent I am not discussing a specific powder or desired weight.
It is the adjuster front or rear orientation that is the question. With the adjuster to the front and aligned with the handle the powder is dispensed on the upstroke. With the adjuster to the rear powder is dispensed on the down stroke, the adjuster is now opposing the handle. I have seen it both ways even on the RCBS site and even in their owner’s manuals and documentation.
So the poll/discussion topic is: In your experience which way works best and why?
So to keep the poll simple here are the choices:
Front= Both adjuster/handle to the front, dispenses on the upstroke
Rear= Adjuster rear/handle front, dispenses on the downstroke
Depends= Rotor dependent, works better one way or the other with the lg/sm rotors
No opinion= Never thought about it either way and use it the way it showed up.
left is front config right is rear config
