I wouldn't. Because 1 grain of powder could be the difference between blowing up your gun or not. Best to get one made for powder.

I wouldn't rely on a quarter for calibration. Actual calibration weights would be best.Quote:

Calibrate your scale to always be sure. They sell weight kits if your scale didn't come with one.Quote:

It’s always better to use check weights that are known to calibrate a scale. A good scale and or a set of check weights is much cheaper than the visit to the ER if the gun blows up.

I calibrated the scale with a weight and its off
Toss it in the trash. You don't want incorrect powder weights. What one are you using?Quote:

Definitely trash it. Scales aren't as expensive as an ER bill, your gun or your life.Sent from my SM-P905V using TapatalkQuote:

Then pick it up; let the scale clear; and then weigh it again and get like 115.8 gr and do that over and over and get a different weight every time. I tried it with others things and could never get the same weight twice from the same item. I shelved it and got a beam scale.
I have sense bought a RCBS Chargemaster Lite and have checked a couple hundred throws from it against my beam scale and it is very good, so in my mind with Digital Scales, you either get really lucky or you get what you pay for.
I have one of those tiny scales. 'Bout the size of a cigerette pack and a little thinner.
It seems pretty accurate, but I use it for weighing bullets only.
I believe that it came from Harbour Freight. It came with a 500gr check weight. --- SAWMAN
I've often wondered about the check weights myself. HahahaQuote:

To my surprise the FA scale measured several different calibers of bullets the same repeatably to +/- 0.1 grain and matched the RCBS scale. Makes me wonder if I was doing something wrong before (like not calibrating it right, or not letting it warm or) or maybe it just needed some time to break in or something.
Temperature does make a difference. Since my building has ac and heat i get them to room temp before i use them. No i don't leave the heat and ac on all the time.
