I have a Lyman that I like a lot, it has a trickler that mounts on it.

I set it to undercharge as close as I can and then trickle on up, fairly quick.

Charagmeast 1500 with the mods is a lot faster than the Lite though they may come out with access to change parameters in time.

That said, what is not stated is rather than the calibration aspect, you need to know what your pan weighs.

All scales drift, the more costly the less drift but they all do.

The easiest way to deal with it is to zero the empty pan and note that weight when you take the pan off (mine is 149.9)

If it moves to 150 when the pan is off, I adjust the charge down 1/10.

If my power charge was 55 grains, I then charge it to 54.9.

Once it moves to 150.1 with the pan off I zero the pan again. I can do it 2/10 lower, but I think that's enough offset.

I can do a pan zero and weigh the adjusted charges and they come out right at 55.

While it sounds annoying, if you try it, its quick, easy and takes almost not time and you can keep rolling quite fast.

I am about as fast as the Chargmaster Lite. I am going to watch it and see how it does and maybe buy one for convenience (pan zeros will still apply)

Its smaller and fits my bench space better, it does have a tube mod so the straw is not needed. Otherwise the 1500 is currently faster (with program mods) and by a good 50% it looks like.

Part of my job is calibration instruments and the technique was devolved as a variation of that work.
