   Ja, maybe JSB pack their tins according to weight?
Heavier projectiles are larger and come in 400 per tin, it is also a slightly taller tin, more space inside.
Guess they cant get 500 of the bigger slugs into the smaller tin.
Just looking at some .22cal monster pellets, same small tin, 25,39gr pellets, 200 per tin, works out to about just over 5000gr's of lead per "small" tin, regardless of caliber or pellet weight. 

There is also a price difference, the 10gr/500 tins are $43/tin and the  13.43gr/400 tins are $39 per tin.
Works out to 8.6c each for the 10grainers and 9.8c each for the 13grainers, got to pay a bit more for those extra 3.4grains

	Spent the morning at my range office sounds funny but its work for me, Luckily I enjoy what I do! Retuned the wildcat to the 10.03gr Knock out slugs. I couldn't get the extreme spread lower then 4, but I think I'm trying to chase perfection and one hole groups. Should be happy with what I achieved, because I guess its not bad at all. Got the group down to 5.5mm center to center, and almost a one hole group. Time to find some more bunnies and continue testing. Next question is, down to what velocity will they still mushroom...?

	Ja it has to do with regulations from the Czech government. Because JSB pellets are manufactured in Czech republic, I believe it is a code to indicate which caliber and class of ammunition it is. I guess rim fire would probably have a different code? And military ammo another code...??? Edited by RangerPete - 21 Oct 2024 at 5:25pm

	It's got something to do with some regulation the Czech government has to follow impossed by others Got board going through their regulations trying to find out what exactly. Think it's some sort of proofing mark for quality or pass for a manufacturer. They do have some interesting air gun laws mind.

	Well, that is one helluva list of defns Kruzaroad! The M no. meaning is a secret huh? Just gummint codes probably with no logical meaning assigned by the Head Gummint Bean Counter... God I miss working for the gummint, driving around in the 4WD all day, (Kruzing da road) easily keeping the boss happy by every now and then pinging a poacher. But with my big mouth there's no way i was never going to get promoted...and it took dumb me 11 years to figure out that you must tell the boss what he wants to hear rather than the reality of the situation. No regerts though - I'd likely be useless half dead and rotting wood by now if i was still working for the gummint. Edited by JasonEdward - 21 Oct 2024 at 2:30pm

Not accuracy as thats gun dependent, but quality testing
