Any Experience With These Check Weights (Lyman)

[Potatohead]

Hey fellow (re)loaders,
Anyone have this lyman check weight set? A fine time to ask, as it's already ordered.:banghead:

I dont imagine one is likely to get a "bad" set of check weights(?) so I got these because they were cheap (and they threw in some tweezers, how could I resist?). I thought it wise to run it by you all, as I can probably still cancel it today. (ordered last night)

PS I think their is a chance I might take my electronic scale out into the yard and commence firing. I can weigh the same thing twice and it will read different both times..:banghead: I might be the first person to shoot his scale instead of his chrono. Back to the beam I guess, but I need some check weights.

Don't cancel the order. I use the same check weight set.

The price is fine if you have Amazon Prime membership.

Optics Planet has the same set for $24 but you have to add shipping - http://www.opticsplanet.com/lyman-scale-weight-check-sets.html

Let me check to see if Optics Planet is still offering THR discount.

Awesome news! Thanks BDS. I'll just let it ride.

I am not aware that consumer level check weights meet an industry specific standard (i.e. a +/- range), or even if there is one.

Remember that check weights are only as reliable as the company that manufactures them. I'd bring those Lyman checkweights to my local pharmacy and get them weighed on a calibrated dispensing scale. Then convert from grams to grains.

Only then will you know what mass your Lyman checkweights truly are.
Pls let us know the results.

Good point.

My Lyman check weight set with my Pact Precision scale are exact with all the weights. 10 equals 10 grains and add a five or a one and it's exact all the way up to the 50 grain weight. I know my scale is accurate and the weights make me confident with my Pact scale. That's the reason for the check weights is to verify your scale is accurate.

Toss a bullet on the scale making sure the scale was zeroed, note the reading. Remove the bullet from the scale and make sure the scale is zeroed. Toss the same bullet on the scale and it should weigh whatever it weighed a moment ago. Actually after the first weighing the scale should return to zero on its own. That is a measure of repeatability.

Toss a mass of known weight on the scale after zeroing the scale. The scale should measure the known weight. Try a few more known weights, the scale should read the weights correctly + / - 0.1 gr. That is a measure of accuracy.

When you get the weights do as suggested and take them to a pharmacy and ask them to weigh them and make sure they are good. I have a RCBS set that are very accurate as before I retired I dragged them into the lab at work. The RCBS set looks like the Lyman set and I'll wager 10:1 the same guy cuts to weight in a garage in China.

No, you would be the second person I know of who shot his scale. I had a friend who managed an accidental discharge with a 380 ACP and shot and killed his brand new Dillon scale. I told him to send it to Dillon and they would replace it. He didn't want to as he was embarrassed. I told him fine, give me the corps and I'll send it, what do I care if a bunch of people at Dillon are laughing at me, I get a nice free scale. Changed his mind and sent it in and they sent him a brand new scale absolutely free. So you would be the second person I know who shot his scale.

They look the same as the ones I have.

You need to get another set of weights to check the weights that you bought for checking.

I think they all come from China check weight .

^ LOL.

That's hilarious!

You know you've been doing this a while when you have a story like that!

For cheap check weights you can use new coins.
(Old coins will have had some metal rubbed off.)
Really old dimes & quarters (pre 1965) are silver & won't work.

Penny = 2.500 grams = 38.58 grains
Nickel = 5.000 grams = 77.16 grains
Dime = 2.268 grams = 35.00 grains
Quarter = 5.670 grams = 87.50 grains
Half Dollar = 11.340 grams = 175.00 grains
Presidential $1 = 8.100 grams = 125.00 grains

The Lyman weights are made to class F specs, according to the pamphlet in my set. I looked up the specs.

The 10 grain weight, for example, is plus or minus 0.0000017 pounds. I do not think that your scale is accurate enough to worry about that small amount.
