This thing is so simple it confuses me how inconsistent my results are.
Powder Cop: the notched stem was hanging badly out of the box and continued to after degreasing it. The surface was fairly rough so I polished it with 220 grit lapping compound in my drill. This smoothed it up a good bit. I then installed it in my press (LNL AP) per instructions with wad guide finger thing in place b/c I'm doing .223.
I am using H335 in the powder measure supplied with the press. I settled the powder, made my adjustments, and verified consistency. I get variations every now and then of 0.2gr under to 0.3gr over, but the powder cop raises a different height every time even with the same charge weight +/- 0.1-0.2.
Is it possible that the powder settles into the case differently every time? If I bump the press a few times the o-ring will line up proprerly and other times it drops below the mark! Remember this is with nearly identical charge weights! The case is LC 11 with a target charge of 25.5gr of H335. Has anyone run into this before? Hornady says it can detect up to a 1 grain difference with fine powders in most cases.
