Testing JSB pellets

Today I did buy some JSB pellets and because I had to spend some time at a place where they have some highend scales I decided to do some weighing.

That highend scale needs a check, 26 pellets and the weight increases on each one???!!!

You can find that variation in same batches but not in that order.
 
The results are presented from lowest to highest to make it more understandable. I did recheck five of them and only the last digit did show some minor changes depending on if I did close the glassdoor to the "room" where the scale is situated. It seems as some of the text in the original message has been lost in the editing. I did ask in which increments it would be wise to sort the pellets if I would like to testshoot them in a railgun indoors. As an example, 8,3 grains, 8,4 grains, 8,5 grains or smaller???
 
In your sheet is missing an important data the number of pellets of each weight.

For me the sorting depends on the quality of the pellet, if I find a good die/batch I try to use as many as I can so select them in increments of 0.5 grams but usually put aside everything lower than 8.30 and higher then 8.60.

If the pellets are not very good I use the numbers close to the manufacturer specification guided by the number of pellets in each weight and usually I got most of them close to 8,40 and 8.5

Indoor you won’t be able to determine if a pellet is good or not, if is to shoot BR25 probably even a bad pellet will perform.
I shoot FT with JSB Diablo 8.4 can you tell us the numbers under the box I suppose that is a batch older than 2011.
 
I will try to do some serious visual inspection first and then weigh and sort them. My problem is that I have very bad eyes so a good magnifying glass with lights is necessary. I didn´t really expect myself ever doing this but the more I think about it the more interesting it gets. Those small devils are full of hidden secrets.:confused:

How is it that a bad pellet will perform or what is your definition of perform?

If a pellet is not capable of scoring an "X" then it is not performing, at least not well.

I’m a terrible BR25 shooter my main discipline is Field Target but your approach should be different is not the pellet that is capable of scoring an X is you! :cool:

For me a bad pellet is one that can’t take wind I believe that the main reason is because the mass is out of balance making it fly in spiral, the so called flyers.

I didn’t had the opportunity to test is but I believe that the ‘spiral’ start to open when the pellet loses energy and receives wind so in BR 25 shouldn’t make much difference.

If the pellet is no good neither is the score, much more so in BR than FT.
 
For me a bad or even an average pellet is one that dont group.
99% of JSB made stuff cant get to group less than 1/2" at mickey mouse range, whereas good ones i cant buy wont leave a .22 size hole at 55 straight from the tin.

I have the scale but has not started yet, but I would like to know if a 0.5g increment is widely used and a good starting point, and if not, what is? I've been told that the increments have to be tested out before you know, but a starting point is always nice to start with.

I just realize that I made a mistake the increment is not 0.5 grams but 0.05 grams, you can go lower but it’s very expensive a scale that is accurate at 0.02 gr

Good news, I thought that 0.5 grams sounded a bit coarse. I'll start with 0.05g.
