QYS pellets: head size

[Cavalier]

A bit strange this one. I have decided to try and match batch codes when buying multiple tins of my QYS streamlined pellets, so I have been looking at the back of the used tins I have, looking at the 2 digit batch number that follows the head size, I’ve noticed that the head size on 2 of the tins, printed on the top states 4.5mm head size but on the bottom of the tin, if I’m reading the batch code correctly, it is printed with a head size of 4.49mm. Anyone else noticed this?

They do either 4.49 or 4.50 head size. My Ghost loves the 4.49’s. My HFT500 loves the 4.50’s. I have to flip the tin over, to make sure I’m picking from the right tin
