Its been A bit hot in Fresno, in the triple digits, so I have not been in much of a hurry to spend the day at the range, but that does not mean that I couldn't play with my powder measure a bit, to see what the average value per click is, over a wide range.
As I wrote in a previous post, this powder "likes" a simpler measure technique (than 133) for best results.
Doing a quick test, using a Pact scale that has just come back from the factory, and being careful to check for zero, and do some spot rechecking. I found that my Harrell measure (the one with the spheroid body, and roller bearings) which is set up with six graduations from number to number (old school benchrest, number to number is one click) over a range of settings that covered eleven clicks (form 46 to 57) it worked out to an average of .55 grain per click, or .09 gr per detent (sixth of a click).
After running this ultra unscientific series of throws, paying close attention to technique, I can think of no earthly reason to haul a Chargemaster to matches, if this, or the Canadian 2015 is your powder of choice. I should also mention that with the multiple detent ball and spring setup that the Harrell measure uses, slight variance in detent hole spacing might produce some variation. As it was, the jump from click to click only varied by .1gr. with six of the one number increases resulting in a .5 gr. increase in charge weight, and five resulting in.6gr increase.
(Note: Yes, I know that a more sensitive scale would have been better. I used what I have.)
