Re: Powder dispencer question
I haven't heard mention so far of the powder you're using, and wonder if that might not be the problem. If your initial loadings was with a ball powder or even a very short-cut extruded tubular, and you've since changed to a longer extruded type powder, that may very well explain the difference. Some powders meter very well, while others are a bit more troublesome. Some are a flat out pain in the ass. The measure you have is most likely a BR-3, or possibly a BR-30, but I doubt that changing the rotor will make any difference in the ability to meter consistent charges. As has already been mentioned, a smooth, consistent operation will contribute greatly to more uniform charges, but you have to accept the fact that not all powders will run through a measure easily. In most applications, the variation of a couple tenths won't make any difference. But if you wan the absolute finest in consistent charges, you're back to weighing individually, and adjusting with a trickler.
