With all due respect I believe you missed the point of creating your own check weight.

Hilarious!
That's what I was trying to say! Dido.exactly, we are not selling gold or compounding pharmaceuticals so whether a checkweight is 45.2 gns or 45.3 or 45.1 is not relevant to what we are going for. What is important is that same check weight still registers 45.25 grains today, tomorrow and a year from now. I find either a .22 LR or some other 40gn bullet works well for me becasue that is close to all my favorite loads
I also calibrate my scale with 30 grams rather than 100. In the Navy we were taught that a torque wrench is most accurate in the middle of it's range and figure the same logic applies to load cells, maybe not but scale seem sensitive enough to me
100grams is 1543.246 grain. Kinda far away for checking powder charge linearity

Sorry you feel so strongly about my posts. Maybe i should be on your ignore lists so as to not cloud up your reloading prowess. If your scale check bullet varies in weight you should invest in a new scale.
I have a TROEMNER 100 Gram CLASS 1 CALIBRATION WEIGHT. Class 1 would be the the most precise. (I think). this is for use on my fx120i. using this i found that from the retail place i purchased it from, their calibration was off 0.644 grains.
You can sometimes find good, used deals on Ebay for Class 1 calibration weight. I picked the 100 gram because it's set by default. you can change to the 50gram weight.
The guys using the Aluminium powder cup from Area419 on The FX120I would be getting close, that cup looks heavy..100grams is 1543.246 grain. Kinda far away for checking powder charge linearity

I didn't get rubber gloves. But it came with angled tweezers.Same here. Class 1 I have a troemner. They are like 80-100 bucks. Come with a glove to pick it up too.
I'm not too concerned about an inert chunk of metal somehow becoming unreliable.
Exact weight matters none. The best check weight is a bullet that you scratch the weight into and keep with the scale. No need to waste money on check weights
How do you scratch the weight, and correct for the change in weight caused by scratching the weight?
Doesn't matter. If the weight balances at a specific point & the check weight matches, then when you return to using that load, you set the scales for the mass of the weight you want to use.and how do you calibrate the balance that you use to weigh the weight before you scratch the weight?

These types of sets are very accurate as they were made to calibrate actual pharmaceutical scales. These weights were in common use up through the late 1990's when digital scales became the norm. The set above probably cost over $400 when brand new.
I have a set of these: https://www.ebay.com/itm/Troemner-A...d:g:vvwAAOSwpHpbCZi4:rk:2:pf:1&frcectupt=true
They are actually 2 complete sets, one is metric and the other is in the traditional apothecary weight system which is based on grains.

Nothing is wrong with them.What's wrong with the RCBS or Lyman check weight sets at around $40? I've checked my set against a good calibrated lab scale and found they were too close to worry. They are grain weights and by combining weights you can make up a weight very near the load you intend to use. If you want to be using a powder load of 36.5gns just make up the exact weight (20,10,5,1,.5) with the check weights and make sure your scale reads zero and repeats at that weight. In fact, you don't even need any numbers on your scale.

The guy posting the ad doesn't know what he has. I have this exact set. The upper row and midlle row of smaller weights are all in Drams, Scruples and Grains.I must be missing something. I see no check weights in grains there.
