Powder Measure Redux Part 6: Redding Competition 10X-Pistol and Small Rifle Powder Measure
Redding 10x is designed for pistol-sized powder charges. At $180 street price at the time of the writing (November 2013), it is, as far as I know, the most expensive
powder measure designed for pistol.
While running a completely unrelated experiment testing powder scales, I happened to accumulate statistics for its accuracy
dropping Titegroup powder. Titegroup has the same composition as most pistol powders - tiny flakes - and measures really well.
Radwag AS/60/220/C2 semi-microbalance scale was used for weighing the samples. Here are the results - most numbers are
So the estimate of the standard deviation of the population is 2.4mg, or 0.037gn. Interestingly, it is a bit worse than that of
Dillon XL650 powder system, which measures at 0.028gn.
So on one hand, it is definitely "good enough" for competition loading, and on the other hand it offers absolutely no advantage over the progressive press - and
costs almost twice as much as Dillon's quick-change system (which includes their powder measure, the toolhead, and the toolhead stand). I guess - save your money
for use elsewhere!
