Chargemaster/Sartorius scale combo?

[usafabrad]

Hey all im brand new to reloading, and ive just been trolling around looking at measuring equipment. Has anyone tried using an RCBS Chargemaster or a benchrest-type powder measure (redding, etc.) feeding into a sartorius/acculab-brand scale and trickling to get .01gr-accurate loads? Just curious if its even a legit idea in general.

Flame on, im here to learn...

Prolly be better off using any bench powder measure to throw your target load minus (eg) 0.2gr and use a hand trickler. The key is how the scale responds to trickling - presumably pretty well in your example case.

This is the way to go if you need spot on charges. Just for my knowledge, do you really think that 0.01 - hundredths of a grain is really necessary?

Seems a bit obsessive/compulsive to me, but, its your bench.

I do use a Chargemaster and then a Sartorius to check the load and a Omega trickler if I need to add a grain or two. I do agree this is overkill, but I find my Chargemaster jumps around enough I just don't trust it. I have just started using Static Guard and am hoping that helps with the Chargemaster.

Chargemasters aren't the best of scales.
Did this for an ammo manufacturer. Controller feeding in the case, measure powder onto the Ohaus scale, dump into case, next. Best we could do was 15 seconds on one scale, which wasn't fast enough. It was extremely accurate though.

In theory, I'd *love* a scale with .01gr accuracy. I also would want it to respond instantly and accurately to the trickle of a single particle of every single powder.

I don't know that any such scale exists. If it did, I probably couldn't afford/wouldn't want to spend that much for it.

If I could acquire one, I don't know if I could control room air currents and my own breathing . . . nor whether humidity has any effect on what my target weight should be that day vs the day the load was "established".

I expect that affordable scales will get better over time, but frankly I think .01gr accuracy is currently beyond my price range, patience, interest, and practical need.
