Looking at getting some scales. I've seen a set that go from 0.001g - 20g. Would these be ok for weighing in grains?

they need to weigh in 0.001g increments, not just down to 0.001g, that's not the same thing

​what they need to do is weigh the same pellet the same weight 3 times. That's the trick with getting good scales

I'm sure your scales there could measure to the fraction of a grain...:grin:

Scales arrived. What spread would you say is exceptable? I'm getting 8.36 - 8.6 I'm keeping anything from 8.4 - 8.48 for comp use.

To be honest i rarely bother these days. Sizing made more of a difference than weight. And then I don't often do that now... because a good batch trumps all.

I'll go through it for something like the worlds maybe... cant do any harm and its a good way of inspecting pellets.

I tried some weighed pellets on Sunday and it really made a difference,no flyers and more accurate. 5 shots on the chrono showed 1 fps variation

I used to put mine in 0.1gn brackets. With a good batch that would straddle say 0.2gn and there'd be a small amount either side that i'd use for something or other uncritical. With a bad batch I could see a spread of 0.4gn with a few extremes. 

 

If it works it works. I'll never knock someone for trying to make their ammo more consistent. That said, if you're falling out the bottom of a kill or going out of the top, it aint that. 

Worth playing with a sizer as well if you're into pellet worrying... that did yield a lot in the Walther, but it Daystates didn't seem to like it, and the Steyr didn't seem to care.

But if you are going to test, face the enemy. Forget 5 shots. You can flip a coin 5x and get it the same way up. Do 10s, 20s, 40s. Get some data where chance is less of a factor, ideally indoors. Takes time to do this stuff well, it pays dividends... you either find you've struck gold, or find that you're just polishing dirt. It gets real fun when you double blind test someone. I used to make up bags of test pellets, each with a different set of pellets in, then write down what they were, get someone to take out the label and write a random letter on them, take the letter out. They knew which was which, I didn't. What i then picked was what I thought was best. That can be very interesting.

I have thought about a sizer but like you say not all barrels appreciate the effort.

Scales arrived. What spread would you say is exceptable? I'm getting 8.36 - 8.6 I'm keeping anything from 8.4 - 8.48 for comp use.

 

I used to batch a tin, so go through and sort out all the pellets into piles going from say 7.9gr to 8.9gr. The vast majority would be in the 8.3 - 8.6 range, these I would put into individual tins so I'd have 8.4's, 8.5's etc then I'd only use that one weight until they were all gone, then go to the next batch weight until they were gone, etc. The ones either end i.e. the 7.9's and 8.9's would simply be binned. So out of a tin I'd probably get 400 that were useable in competition.

 

These days I just open a tin, stick in 6 drops of FP10, close it up, shoot them straight from the tin and have a life...:grin:

I tried several models of those scales and unfortunately all of them gave me different weight for the same pellet very time....

 

The scale that most serious Benchrest Shooters use, at least here in the USA is the GemPro 250...Not a bargain but not expensive either and it is very reliable...This

scale can measure .01 grains (1/100th of a grain) but most shooters set it to measure .05 Grains; at 25 meters (BR. Distance) pellets within 1/10th of a grain will shoot identical

and .05 is half of that...Very possible this setting is what is required for FT to 50+ meters.

 

GemPro 250: https://www.ebay.com...ro 250&_sacat=0

The only problem with weighing quality pellets these days is that they're so good it's pointless.

 

I have a very good set of scales that I use for powder measuring and taking say some AA Fields or Snipers, I can individually weigh out ten and they'll be within a fraction of a grain, then if I stick all ten on the scales it averages out perfectly.

 

I do this for a fresh tin just to make sure they're within tolerance, but as for sitting there weighing every one, no not these days.

 

But, I do size the pellets. I know there is a school of thought that the pellet is sized in the breech but I'd prefer to know that every pellet is the same size before it goes in the breech. By using a tapered sizer, it's obvious if you get a pellet that is much smaller than the rest and these I bin. All the others get sized, given a quick look to make sure there's no damage to the skirt, then lubed in the tin. Since I've been doing this I've not had one flyer or one pellet where I thought 'what happened there'.
