Fact of the matter is, you;re not even shooting the same chamber/case - so thats a pretty bold statement to make

Regardless of if KG is at a higher pressure or not, can you explain why 67000 was the chosen as the final number? - genuine interest not a dig - because I keep hearing 'overloading' and want to know how we get to a line in the sand that anything over and above is 'overloaded' - This is whats this is all about; Wildcats in general without industry standard data
Was it a accurate load and left at that?
Is it max that the brass will take?
Is it max that the chambering will take?
Is it max the action will take?

Don't know the answers to your questions, but using your example of two different cases in the same calibre, 375 Lunatic vs 375 Terminator (I really was scratching my head as to was this thread was about...:rolleyes: ), one has stated velocity and pressure to achieve said velocity, using the same action and barrel but a different case design. If the other would post comparable data with regards to what pressure was being run then we wouldn't all be wasting time here with what ifs... If it so happens that the pressures are much the same with the higher velocity being quoted then well done to the designers of case X...
