7mm RCM should be detween 284 Win and RSAUM or WSM.
I know most of the reloading manuals put the 284 Win slightly faster than 280 Rem, slightly slower than 280AI.
I know Gunwerks did the 7mm LRM (Long Range Magnum) on the full length 375 Ruger casing.
I'd love to develop my 7mm Std Mag. But need to win not so small lottery.
Parent casings $120 for 20, if i can find them. Plus cost of reamers, etc..
