How Frequently Check The Powder Measure?

[ny32182]

I run a lot of Titegroup through my Dillon, and I'm not at a max load, so if it drifts a tenth I don't really care. Once I'm confident it is where I want it, I only check it every couple thousand rounds, if that.

What I've noticed is that my particular powder bar drifts downward very slowly, like it might register a 10th drop on the scale in 5-8k rounds or so.

I use an average of 5 drops to get a better idea of the actual charge weight that is coming out. drop 5 charges into the same pan, look at the weight, divide by 5.

I run 5 to 20 drops through the measure before I use it. I check a couple to make sure it is dropping what I think it will be to make sure I haven't set it wrong, and then I keep an eye on the measure to make sure the setting on the insert hasn't shifted. Other than that, only once in a while do I weigh a charge.

I do basically the same. After it is settled down,I check every tenth charge as well as the last charge in my batch of fifty. I am using the RCBS Uniflow as well.
