Yeap, correct Skires.

I have also been told in the past a very similar story to that posted by Fatwelshboy. Can't remember from who exactly but probably from Air Arms when I was at the factory a good few years ago. The only addition to that story I can add is about the "hardness" or "softness" of the lead being used at any one time. Somehow it affects the BC of the pellet and that is why the depth of the piercing can vary so much, even on the same die number. I understand that on there initial test runs sample are taken to see how the pellets fly in-particular with regard to the height/drop at a set distance. Now can't remember which way round it goes, but if the pellets strike high using their test guns at the set distance, then either the depth of pierce is increased or decreased until the pellet strikes on the horizontal line that they expect. Hope that makes sense!!!
