    They actually sale weights to check your powder scale. I think I purchased mine from precision loading. Josh

    To check your scales, get some new dimes. They are 35 grains each.

    I found a small brass die at a hobby store, I brought it to 3 pharmacy's in my area. Had them weight it. it came out to 1.001 1.0003 1.0038 on their scales. I brought it home and it came out to 1.003 oz on my scale. The check weights can be purchased also.

    Usually, quality retail rifle bullets are quite close to the exact weights, especially the "Match" ones. Military stuff is all over the place, so don't try them to check a scale. I have a couple of sets of check weights. One is from Lyman and I believe the other is an older set from Ohaus. I use the Lyman set often, to double check all of my scales on occasion.

    Years ago when I got a new Hornaday scale, I went to a local scale company, Toledo Scale, who specializes in calibrating scales for factories, hospitals,etc. Gave them a new dime and quarter. Dime was 34.65 grains, quarter was 84.95 grains. Didn't cost anything, they were happy to do it. Wayne

    Rifle bullets work fine. If you don't have any I'm sure someone at your club has a few you can have. If not I'll send you some.

    Lyman sells a set of check weights around $5.00 most mail order outfits carry them. They are very accurate and allow smaller weight checks, 1-5 grain and 10-20 increments.

    I have an assortment of jacketed bullets that I use for check weights and use the one closest to my intended powder charge weight. For most shotgun charges I use a 25 grain .17 cal bullet for the check. The dime idea sounds good too.

    I too have always used jacketed bullets to check my scales.

    I don't think being off by .1 or .2 grains is going to matter much. I do not load anything to maximum.

    As usual, I agree with Quack Shot. #1,It's a good idea to have a set of check weights. As a second choice, use a good brand,such as Berger,target bullets. They are usually right on the money. This includes most brands of target bullets.

    I find it difficult to suggest using bullets to check your scale. Other than custom benchrest bullets, Most manufactures have a tolerence of + or- .3 to.5 grains from the advertised weight. I worked for a company that makes some of the best match bullets and they were + or - .3 grains.

    I was at the Post Office today and while at the counter I ask if her if she would weigh my dime. She did and said it weighs 10 ounces. I said 10 OUNCES?

    She replied 10 ounces.

    Hummmm

    I said thank you and left.

    I thought it was interesting that some of you use bullets for checking weights. So I checked some .223 I got laying around:

    A 50 gr. Sierra Spitzer weighed 50.1

    55 gr. Hornady SPSX weighted 55.0

    55 gr. IMI weighted 54.6 (figures they would be light)

    62 gr Speer weighted 62.6

    77 gr Sierra Match weighted 77.2

    75 gr. Hornaday Match weighted 75.1

    Its been raining today, Wayne
