Do you ever wonder why JSB states pellet weight to the hundredth?

I do. Something like 7.87 mathematically implies an accuracy of +/- .01. So they should be 7.88-7.86. Ever see a tin come out like that? Not me.

Something like 44.75 mathematically implies an accuracy of +/- .05. So they should be 44.8 to 44.7. Wanna see how that works out in the real world?

This tin sorted everywhere from 44 to 46g. And the bell curve certainly isn't over the 44.75 area. If you randomly grab from this tin I can certainly explain the "fliers". Personally I think labeling pellets to the hundredth is a joke given what comes out of the factory.

I cant believe they dont make single die and or matched die tins. Alot of people would pay extra to be able to purchase a majic tin of pellets for precision work.

I hear you!!! Thats why I dont sort my pellets. I will sort em on rare occassion depending on what Im doing. But its rare.

If you are shooting at 20 yards in your backyard or plinking cans, sorting is pointless. If you want to consistently make headshots at 50 yards and beyond or are target shooting for accuracy, weight matters. I took the lightest, two medium cuts, and the heaviest and shot 9 round groups (what a RAW 30 mag holds) at 50 yards. We had a storm front coming through while I shot these, so wind was changing POI and I didn't bother to try and read it.

I wasn't happy with target #4 so I reshot the same weight on target 7. Targets 8 and 9 are the same weight.

If you want don't mind that 'flier' at 50+ yards, shoot right from the tin. If you want groups a bit bigger than the pellet, sort.

It seems the assumption is that the weight difference is equal to size difference. That having a tighter or looser head or skirt size relates to weight, e.g. heavier equal larger.

Considering we are talking a couple of tenths of a grain, it could be very possible those differences are not in direct relation to head/skirt size, but also overall length or thickness of walls. Said another way, the amount of "extra" weight might not all be going to an increase in the diameter of the head/skirt. I think the idea that size and weight are tied is right, but it would be nice to see for sure or at least understand how likely weight is to change the head/skirt diameters.

It would be nice to understand it completely.
