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.
Me too.Quote:

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:P 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.

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

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 scalesQuote:

I know the instructions say don't touch the locking nuts but..... need to try this bullet trick as above.
They both read zero fine. Any suggestions guys cheers
Didn't Tussock or Gimp film themselves shooting their Lee balance scales?
I was tempted to do the same to mine, I think I gave them away for free in the end.
Have you checked both against another set?
My ohaus came with 500,250, and 25 grain tare weights. They are brass so tarnished now even so the 25 gr now weight 25.2. You can buy calibrated weights but projectiles especially sierra seem an excellent idea. Sierra smk appear to be so consistent in weight.
No but not a bad idea thanks!Quote:

You can average out the error by weighing 10 $2 coins and dividing by ten, but the main thing is to use the same calibration weight each time - it's less about how super precisely exactly 10.00 gram it is, but do ask your local pharmacist to weigh out your $2 coin of choice.
The issue in reloading is consistency in everything, including weighing and dispensing - not so much ultimate accuracy as to exact weight in grains in perfect keeping with an official reference standard. Should you discover your powder charges were 15.1 grains rather than 15.0 grains, this may be an irritating discovery but not a shooting accuracy problem... as long as they were all 15.1 grains.
I agree with whats been said but due to the difference between my electric and beam scales I've ordered a set of test weights. My been scales did slightly alter ( not as bad as electric do)but an email to rcbs and a free set of agate bearings are on there way. apparently they wear and mine is a very old set. Great customer service. What I also do once I settle on a load I search my boxes of nuts and bolts until I find a nut close to that weight and then without altering the scales from the loads weighed I file the nut until it matches the powder weight and use this each time for calibration of that load for that caliber or bullet weight. I write on each with a marker so I know what each one weighs. As has been said it doesn't matter if your scales read different to another as long as you load the same for each batch
Year I get all that....but frustrating if the book says load 26.5 of such and such and your loading 23.8 if ya know what I mean.
Being fussy as dose not help:ORLY::P:pissed off::wtfsmilie:
Ok I'm a little OCD just don't tell the wife:o
Benchrest shooters nearly all dispense straight from a powder thrower such as a Harrell's. Most of them seem happy with up to .2 grain variation accepting that it won't make the slightest bit of difference up to about 200 metres. There are too many other factors involved.
Long range shooting is a different matter.
