Long range build 7mm RM vs 300 WM

[Varberger757]

Nope, 2 different cases. They are both based off the same parent case = .300 H&H. But that's about it.

Sorry, but that's wrong! Parentcase for both 300WM and 7RM is the 375 H&H Mag.

I know this, however, both the 7mm RM and .300 WM derrived from the .300 H&H case. which came from the .375 H&H case. So, if you want to get super technical, they all came from the .375 H&H. So, we're both right.
