I have an RCBS Uniflow Powder measure that I bought second-hand in 1978 or 1979. The Uniflow was still new in the box. I know this since the seller bought it along with equipment when he wanted to get into reloading and stored it in my father's storm cellar. He unexpectedly became a father and sold me all of his reloading equipment (under the circumstances, I paid him near retail price).
I have used this Uniflow now for 40+ years. Most of this time has been metering IMR powders.
I learned to spot-check the powder throws because one in every 200 or 300 would turn up "light". The next throw would turn up "heavy" by almost exactly the amount the prior throw was "light". I usually throw charges slightly "light" and then trickle them up to the desired weight so this was a minor inconvenience.
But, in the last year or so, the "light" then "heavy" throws are now happening about every 25 rounds.
Has anyone experienced this?
Do you know what's causing it?
Can it be fixed or do I need to contact RCBS for assistance?
Thanks.
