Best 7mm out there now

I often wondered years ago how it would work to use the .300 Win Mag case as a 7mm. I wonder the same thing about the .375 Ruger case since the PRC is shortened. Maybe I should just build me a 284-375 Ruger in a Magnum length action. Quite sure it would probably come close to matching the 7 RUM, and maybe better the STW?

Edit: I see Gunwerks did just that and call it the 7 LRM. I've been a fan of the .375 Ruger since it came out, and hope to add a .416 Ruger too at some point. But I believe I have found my 7mm!
Very interesting concept and cartridge design!

I may just build me a 7-08 with the CM shoulder like I made in this pic. 6.5 CM, 7 CM, 375 CM

Give it a 1:8.5 twist and just send it
 
I was looking at this. The 7 WSM has 11-12% more speed than the 7-08, and the STW has 14% or so. But the WSM does it with 33% more powder, and the STW does with 40%+ more powder. Makes the WSM enticing for sure.

Wsm is a beast.

175g bullets at 3000fps (24") tough to beat (for shoot ability, efficiency, and downrange performance with softer LR bullets).

Edit….but brass sucks! ;)

Howdy Overkill - Did you mean to say, "but the WSM does it with 33% LESS powder"? Srry, it's late and i'm kinda slow...
 
I have said it before and I'll say it again, the 28 Nosler can push a 195 grain bullet at over 3000 fps with no pressure issues and that pill becomes a lazer beam
