That's my happy place, within the same vein!
There’s quite a few reasons they call it the 7x300 Practical ! Ha
My 1885 7 Rmag Stretched out to 7 STW wasn’t accurate enough to really make use of the extra velocity, If any. So off it went, now I see why.
7x300 might’ve been a great choice.
I think a lot of it is about the throating.
