measuring pellets

I've seen so many posts where people show a tin of pellets in little lines, according to head size. The same picture shows a digital veneer caliper and measurements of, say 4.50, 4.49, 4.48 and so on. I have a quality digital caliper and all I can say is, I simply can't believe these folks are serious. There's just no way you can measure a .177 soft lead pellet accurately down to a 10th of a mm. Please enlighten me if I'm all wrong about this. If there is a way to do this with a digital caliper, I will go on record and say, you must be nuts to carry things that far. :?

I think the factory makes them the best they can then use a laser measure to sort them mechanically into the sizes on the tin. I dont think its possible to measure them at home to that accuracy either.
Some JSB tins are "specially selected" but even Czech labour is too expensive to sort 500 pellets by hand!

allways thought the size referred to the size of the die used, not the actual pellet

I have to agree. You're quite likely to deform them slightly, making the whole exercise somewhat pointless. I can't actually say that I'd "rather watch paint dry" than measure pellets, but I'm sure you get my drift.

I love production machines. It was my job for 8 years. maybe I can see through the machinery. Point is they make them like shelling peas and you cant do that in a batch to 0.01mm.

My point was that the fellow that always shows the pictures of sorted pellets can't possibly measure with a veneer caliper. He has said that he locks the caliper to a size and then checks pellets for ones that just fall through the jaws. There's just no way he can be accurate to .01 of a mm. His posts always have a very negative slant against JSB pellets. I once saw that 220 or more of the 225 shooters at the World FT comp. used a JSB variant and the very few that didn't were at the bottom of the scores. He's convinced that the tight fit of a Crosman Premier means accuracy. I'd like to run a test where he shoots groups with his gun, but doesn't know what pellet is in it. My bet is he'd do better with some JSB pellet. The mind can do strange things, including making you not shoot as good just because you think the pellet you have is less accurate.

It can also work both ways. Mind over matter and self belief :mrgreen:
