correct. It’s a pseudo-ackley of a 375HH. So if you shoot hh, it will fire form. Will a HH round regulate anymore? Probably not. Will a weatherby round regulate? Probably not. Will you have to load a custom never-thought of before loading in a 375w case to reproduce 375hh ballistics? Probably.All the 375 Weatherby is is a 375 HH improved.
But I agree on questioning if the barrels are still regulated to the same point of aim at X distance
