Well maybe not a tale but how about a tell...

I’ve been using a Lyman D-7 scale for the last four years and while I believe I had it set up correctly I just do not trust it. When I say do not trust it is an afterthought when I recently came across an RCBS 1010. When I got it set up, adjusted and tested I tried it out with my 223 load in my Lee powder throw that was supposedly set at 23g IMR 3031.... we’ll it weren’t!!! It was actually 23.4g (if the RCBS1010 is right) ....

So in all of your infinite wisdom, which one do you think is the best, should I keep one as a back up or scrap em both and get another of better quality?

As always, thanks in advance. ;)

Precision trumps accuracy. If you work up your loads it doesn't matter if your scale is off a long as it's repeatable. Use whichever you like best!

I was thinking along the same lines, I first have to know what is the right weight though. I’ll get a weight verified tomorrow, thanks.

That is not a weight check, it is an auxiliary weight to ad capacity to 1,010 grains.

Thanks but no, I'll wait for the "No Error Deal". I've got a set of RCBS check weights coming this week. :bigsmile:

I'm going to set up the 10 10 and use it and probably sell the Lyman later on.
Thanks for all the feedback folks. :thumbsup2:

If it's a known weight and within the range of your scale, it doesn't matter what it's called, it can be used for a check weight.

Thanks, but calibration with a 250g +/- weight, nah. I have a set of RCBS check weights coming so I’ll wait for the real deal.

Scratching my head here about your objection. If that weight is intended to increase the capacity of the scale, it's just as accurate as the check weights. And there is nothing wrong with calibrating with a 250gr weight (unless you're using a scale that doesn't go that high, but the 1010 does).

My check weights are in grams so I just convert to grains after I have used my 1010 weight for a quick check. I have recalibrated analytical scales so a powder scale is easy.

Just my personal preference is all. I received the check weights and the scale has been calibrated to my satisfaction. Thanks to all who posted comments. :thumbsup2:

Was actually the method used to calibrate pipettes for FDA compliance.
