Calibration Weights Needed

^^^ Best way to do this right here ^^^
I have an assortment of bullets from 40.0 grains (even) to 200.0 grains (even).
Whenever my scale is moved or basement floor heaves (its a Regina thing), then I re-level my Fx120-i and make sure its spot on with the bullets.
If my FX120-i is perfectly level every time then its perfectly repeatable every time

You need to check numerous bullets to find one that is bang on weight and save it for next check.
How does one check a check weight?;-)
Personally I'd never calibrate a scale with anything other than certified calibration weights.
My Chargemaster and Fx-120i both came with them.
I weigh and measure bullets for input into QuickLoad and there can be quite a bit of difference from one to the next.
YMMV

The problem with the calibration weight that comes with the FX-120i is that it is, I believe, 100 grams. (And I don't think it's certified.) I'd like something closer in weight to the charges I'll be weighing--3-5 grams (or roughly 45 to 75 grains)--to check before weighing.
Have you tried amazon.ca ?
I have seen those on Amazon.ca when I was buying a small scale for weighing my flour gold after a days panning in Yale.

Yeah, those look good and they're cheap. I was hoping for weights in grains, but grams will work with my scale too.
Read the reviews before buying cheap calibration weights
———————————
Half of the large weights are off by 0.1-0.3 mg small weights are much worse. couple are off by 25%!!!!!!!!!!!!!!!!!! quality just is not there. fabrication is lacking. burrs on the metal. shapes don't fit respective compartments. box is kinda crappy too, small weight lid doesn't close, tweezers are not precise enough, unable to pickup half of the small weight because tips are too thick and rounded.

Has anyone tried the Lyman set?

I'm encouraged by this review:
but currently I haven't pulled the trigger and ordered them.

That's good advice. I looked into the RCBS and Lyman calibration weights, and the reviews of the Lyman weights were pretty negative--off from their stated weight. On the other hand, precision of check weights might not be all that important. Let's say the 3 gram weight is off by .003 g. You weigh it several times and perhaps on more than one scale, and come up with the weight of 3.003 g. for that check weight. You make a note to the effect that that particular check weight is actually 3.003 g. rather than 3.000 g. So henceforth, just use it as a 3.003 g. check weight and make sure your balance is showing 3.003 g. whenever you weigh it before weighing your charges. If it's continually showing 3.003 g. on your balance, then you have calibrated your scale for that weighing session, n'est-ce pas?

You just might be looking for a level of precision that is beyond what your scale can accurately determine and also is beyond the level of error built into the rest of the equipment, so you won't know if it was a measuring error or some other error that caused the discrepancy in whatever data you might be measuring.

Been using that set for years. Works great, after I calibrate chargemaster I use those to verify proper weights. Cheap piece of mind. They have always been correct on scale.
Excellent! Thanks for the response. I'll probably just end up throwing in the cart and glad to have the piece of mind anytime I want a double check.
