Thread: Balance scale calibration

Is it necessary to do a calibration with a balance scale and if so what would i use to make sure they are reading correctly. Is there somewhere to get a say a 10 grain weight?

Use a projectile, 55 gr or so
Works for me !

I also use a projectile.

I keep a specifc projectile I write on it its weight, say 155.1gr and check it occasionally.

Should have thought of that. Dumb ass But as i have my first lot of reloading gear on the way i will be asking more questions dumb or not, it is good i have lots of experts on hand for advise. Cheers.

If you need a hand mate your welcome two come out

Great idea. Going to use that from now on

Nz coins also each have a specific weight . Google will tell you what they weigh. All I can remember is the old 50c coin was a half ounce . New ones will be in grams.

Don't rely on coins- just checked.

For baseline comparison,
53 Sierra weighed 53.0
105 A-Max weighed 104.9
145 LRX weighed 144.9

$1 coin should have been 123.45gr but was 124.9 on scale

The only Dumb question is the one you didn't ask.

So ask away.

Welcome to the wonderful world of reloading.

Well, there is. I note on the electronic scales, they provide a 'calibration weight'. On any other beam scale, I'd be very hesitant to weigh a projectile (BULLET) and take that as a standard to check my scale. I recently weighed some reputable commercial 245 gr bullets as a matter of curiosity on my aged Redding scale. They weighed for any chosen bullet,up to 2.5 grains difference in weight from a batch of 500. In powder,that difference could mean an impromtu visit to the ER section of your favourite hospital, if you're already pushing the limits of pressure.
Please bear in mind that because my 'old trusty scale' produced this result doesn't mean that it's incorrect. It's only proven incorrect or correct once measured by a known weight. That's my point, no more, no less.

Within reason I don't think it matters if your calibration is out a bit as long as it is consistent.

Agree 100%, coz you're hopefully working up a load safely using your scales
