Brittany, here's an example from the BASC information sheet I cited: "The mean velocity, measured at a point 2.5 meters from the muzzle . . . " To my knowledge, under CIP rules, steel loads are the ONLY ones that have a velocity limit. And that's how they state velocity will be measured--but only for steel loads. Therefore, ammo makers don't have to adhere to ANY velocity standard on ANY other ammo, as long as those shells meet CIP PRESSURE standards. Which leaves them free to express the velocity of their shotshells (other than steel) in whatever fashion they think buyers are most likely to understand.
It'd be nice if they'd all settle on one standard method of measuring and expressing velocity, as we have on this side of the pond. But I think they like to confuse us.
