So is that how it works? So far I been disappointed with this product, please give me some good reasons not to return it.
The Harrell's powder is a good one and I have tried many different brands and found that I was
the biggest problem with the consistency.
I set up test of 10 charges of different powders and powder measures and tried different ways
of operating the measures and there was a significant difference in consistency.
The Ohas and Harrell's were the most consistant of the measures I tested. (I did not test every
brand available just the ones I had used and kept). but different methods made a difference
in each one.
So I looked for the best method for my measures and found that two taps on the fill cycle work
best and maintaining a rhythm while charging. While doing so ,if any charge doesent feel right
for any reason I just dump it back and recharge the case.you can also double tap the dump cycle
to assure that any and all powder is dispensed. (A few grains left in the measure can drastically
effect the weight consistency.
Starting out I weigh every charge until I get consistant weights (I think the powder has to pack
down in the measure a little before consistency is achieved) then I go to every 10th one and if
anything has changed, go backwards until they are correct again.
I realize it may sound silly but it works for me and keeps my charges at or below 1/10 grain
This is Just what works for me, and If I want perfect weights I single charge and trickle to the
exact weight wanted.
