Which Scale Check Weights?

[Ron Gorski]

i need to buy a GOOD set of scale check weights. Please throw some options at me as to which weights are accurate and reliable.

Also, let me know which weights you would not recommend due to inconsistency of weight.

It depends on what scale you are trying the check(calibrate) that will determine which class of weights you need.

You guys are putting way to much too much thought into all of this!
I just dump (example) 40.0 grains into my pan on a Scott Parker tuned scale now I transfer it over to my A&D FX120, WAH-LAH, it reads 40.0 grains ..... you're ready to go. Now as far as weighing it down to .02 that's ridiculous. I can prove to you that plus or minus .04 in a well tuned rig means absolutely nothing. I've tested during matches just to prove it to my self.

It's January and the internet is a warm place.

Edit it's February 1st and the internet is still a warm place even if I don't know what month it is

I use a 2 gram Troemner weight.

Whenever I get the itch to check my scales that’s what I use.

Class 1? I try to calibrate before I measure any powder. It's pretty quick.

So what is everyone doing to outsmart the anti drift software built into the scale?

Not now- we still think these scales are exact!!

three months ago my pulled 40 grain .22LR bullet check weight weighed 39.96 grains the first day I weighed it. Just weighed it and it weighed 39.94 grains. My powder load has about 35 FPS difference between 37.30 and 37 .80 gns so if my weighed charge of 37.50 is off .02 grains one way or the other I will never notice it. My buddy swears by his RCBS 750 Chargemaster and at 1000 yards can bust a clay pigeon 3 out of 4 shots. It's called load development, you look for flat spots in the velocity curve so you don't have to worry if the load was developed in 30 degree weather and now it's the middle of August

At 1000 yards 50fps less is 12 to 14 inches more drop

Sorry you feel so strongly about my posts. Maybe i should be on your ignore lists so as to not cloud up your reloading prowess. If your scale check bullet varies in weight you should invest in a new scale.

It doesn't bother me if you Ignore my post,I shoot many thousands of rounds at 1000 yards,would not be able to hit targets if scale was not accurate.

ARE those Selfies ?

What's wrong with the RCBS or Lyman check weight sets at around $40? I've checked my set against a good calibrated lab scale and found they were too close to worry. They are grain weights and by combining weights you can make up a weight very near the load you intend to use. If you want to be using a powder load of 36.5gns just make up the exact weight (20,10,5,1,.5) with the check weights and make sure your scale reads zero and repeats at that weight. In fact, you don't even need any numbers on your scale.

Nothing at all,that' Smart People Do.

DUH,if your trying to weigh your 45.25 grains,how do you know your scale is Reading Correctly;With Out Checking the Accuracy of your scale w/ precision scale weights ?? If your shooting at 1000 yards or farther,it makes a Difference,If your trying to hit 55 gallon drum at 100 feet it Doen't.

To me, all a scale weight is used for is to check to see scale is repeating and weighing what I weighed last week or the week before. The 45.25 or whatever weight is worked up to in load development with the scale that I used the check weight on. Temerature and humidity have more effect on your load then a .01 difference in powder change. I use a scale that weighs all the same that day. Humidity in powder can change from day to day. Matt

Not if your in the middle of a node. It's all about tune and not velocity differences. Matt

Does moisture in powder change its weight or burn rate?

I’ll make weights out of washers by filing or grinding them down to match powder charges exactly. These are used to verify that the powder charge is exact and scale is reading correctly. Easy to do then write the weight on it for reference.

That’s a great idea

MINE IS ! LMBO ! PERFECT !

Hi Alan. A customer of mine a few years back dropped off his Redding scale and a set of RCBS check weights. I finished his scale and proceeded to test the check weights. The two 20 grain check weights were .2 grains apart from each other.

Once the disparity is known, what difference does it make? 'Trust, but verify.'

Sorry, I wasn’t clear. There were two twenty grain check weights in his set. They were .2 grains apart from each other.

I always use a 45 pound dumbbell. I tried to use my 75 pound retriever, but he squirms around too much.

I agree, they're not Lab quality - they're cheap, and of course, any inaccuracy is compounded when you start combining multiple weights but .2 in a 20 grain weight sounds like a real lemon. I guess the odd one slips through the net but I'm surprised at that, I wonder if there was some mechanical damage? My Lyman set has a cumulative error of about .07 light reading 210.43 for all 10 weights. (100,50,20,20,10,5,2,2,1,.5) I also have a fancy gram set but to be honest nearly always use the grain set for checking reloading scales.

Got to be better than taking a random bullet out of a box the says 69gn and thinking it will actually be 69gns without weighing it - but as is often pointed out, the numbers mean far less than the repeatability.
