I've been working up some loads using 2.9 grains of Red Dot (for .380). Out of 30 rounds at this charge I got 2 that threw light charges of 1.0 grains. It was obviously not right visually (I check every time) and I'm weighing every charge during workup.
This has me rattled as the powder measure has been very consistent so far.
I've loaded about 2500 .45 ACPs, 400 9mms, 1500 .40s, and a few hundred .38 specials so far (all with red dot; charges from 3.6 to 5 grains) and have never had it throw a light charge before.
Have I reached the lower limit of consistent metering for red dot through the auto-disk orifice? I'm using the small disk and the .43 orifice.
The weird thing is all the other throws were pretty consistent at 2.8 or 2.9 grains. You'd think that if the powder was stacking or getting hung up it would throw light every time or at least more often. Or at least that's how my primitive caveman brain works.
After the first one I thought maybe something mechanical was hanging up and lubed the outside metal sliding surfaces of the measure. Did about 25 more at proper charge then got another 1 grain throw.
Thanks for any advice.
