well i agree with this but i dont like it.(the lrm part) I thought the 7LRM or mabie 7/375 ruger was going to be the answer to my 7mm dreams until i started looking into the brass situation, then i found out otherwise.
Yeah the 375 Ruger case is very well designed and makes for an excellent LR wildcat parent case. Good capacity, very little body taper, 35 deg shoulder, decent neck length, etc.
Nosler was making brass for the 375R initially but discontinued production a long time ago. All that's left is Hornady

I think if Ruger would have come out with that case design in 308 or 338 to start then later on added the 375, the case would be much more popular forcing brass manufacturers to support it.
