Double facepalm with a toe loop

I won't link it, but on a Google+ group I follow, someone posted that they had to disassemble 700 rounds of .223 because "had loaded these .02 grains over what I had wanted to." He confirmed that wasn't a typo, 2 hundredths of a grain over his intended load. Not .2 grains.



Assuming that the poster did not just make up the story from whole cloth - which I really suspect .... There simply are not any scales, mechanical or electronic, in the reloading hobby that are that have the accuracy nor precision to measure to 2 hundredths of a grain. And if someone was actually using some lab quality analytic balance to measure his charges to that precision, he is wasting his time because no other component - not case length, case volume, bullet diameter nor bullet weight - is available in that degree of precision either.

Doesn't the Prometheus measure to that degree? Not that it matters though, because everything else you said is true.

There are scales , but it's a few $$$. Even .2 (depending on powder) isn't life threatening.

I don't know how much a single kernel of Varget or H-1000 weigh, but it is sensitive down to the single kernel.

Totally overkill for ammo inside 400-500 yards.

Yes. And it's beautiful.

I'm not familiar with the Prometheus, but even if a scale displays a value with that many digits does not necessarily mean its that precise in reality.

Not your tradituonal powder scale/trickler.

I saw that post too, found it a bit silly. .02? sheez.

Wow. For .223, I'm guessing he's loading somewhere around 25 grains of powder, so we're under a 0.1% difference. 1% jumps don't usually make that big of a difference. Sheeesh.

Exactly. Although the G+ thread seemed baffled by the idea that one cannot actually measure that "difference" if it actually existed.
