JSB (Polymag) Predators - uniformity of weight

[TCups]

Here is the distribution of weighs of 200 JSB Predator pellets.  Package indicates 8 gr.  Average weight 8.14 gr.  The variability of weights of these .177 pellets is as great as any pellet I have measured so far.  These appear to be relatively hard lead.  Little or no deformity of skirts apparent.  No topical lubricant has been applied.

cooooool. Good info for inquiring minds!

 Thanks, that's good info. Kinda amazing there's such a spread in weight and still manage to hold a reasonably consistent POI.

 I'm a big fan of these. I sure wish they were sold locally, but I'm not gonna hold my breath waitin'. Never happen.

 Thanks again, and you have a good one,

Nice work T, but not sure how to read your graph. I like using the Preds in my springers (both .17 and .22 which is boarder-line heavy for my .22 comfort zone, but......). They're very consistant, and of high quality. Devastating to prey. They work great in my Benji pumpers too!!!! tjk

Thomas:  The bar graph is just the number of each weight of pellet, lightest to heaviest, from the table  to the left. The pellets have a uniform distribution in a bell shape curve, but vary over a wide range.  The tighter the curve fewer, taller bars, the more uniform the pellet weight and less variability from shot to shot.

Here is what the weights of a few JSB Predators I shot this evening in the Diana 48 were, for example, with corresponding velocities and calculated FPE for 13 consecutive shots.  These pellets may be killers, but their individual weight is all over the place.  If I were going out in the field to do some serious hunting with Predators, I would weigh out the pellets first, and take a dozen or so that were all the same weight, having zeroed the scope for that weight Predator.

Very interesting. Thanks for the info.
