This in no way equates JSB with H&N or Benjamin , predator , or others. This example is strictly JSB products . Notably JSB , FX , Edgun JSB , AA pellets. I have sorted thousands of pellets in the 25 cal 25.3 - 25.4g as well as the 33.9-34g weights. Using pellet gage , these pellets ALL come in head sizes of 6.36 - 6.39 mm with THE vast majority falling into 6.37 - 6.38 mm . Now i have seen less variation in skirt thickness between different " brands" than from different tins in the same batch of one brand. I also notice that each tin of FX or Edgun JSB have a tighter variance of size Than regular JSB does. Does that mean they will shoot better in your gun? Not necessarily , your gun has a head size preference , period. every FX barrel i have had enjoyed a specific pellet size just as my LW barrels did. It's just that FX barrels seem to have more flexibility with different head size pellets.
But , back to the pellets , I whole heartedly believe you can purchase any of these brands , and some will shoot better or worse because of the predominent head size contained within that specific tin regardless of brand label. If you sort them based on head diameter , I feel that they will ALL shoot the same to each other. The variable head diameters contained in each tin accounts for the spread on a grouping or fliers. I believe you can mix all these brands together as long as they are sorted by head diameter , as well as weight , and you will have very consistent ammo. I don't think there is ANY difference between all these JSB products.
Now i have NOT had the chance to prove this , but from studying the appearance and measurements of diameter and weight and spotting no significant differences. I stand behind this claim. Now if there are other serious pellet folks out there , which I'm sure there are , I welcome your findings.
