You might look at chambering for a 300WM case but to 7mm. The 7mmRM is a little shorter to the shoulder than a 300WM case. I am not for sure why the 7mm RemM case is a little shorter to the shoulder.
What 7mm magnum cartridge to build?

Personally I'd do a PRC or a Nosler but the Nosler gets my nod. I have one and the only downside is the magazine length. So when the barrel is done I'll put a PRC barrel on it, then build another Nosler with more mag length.

The 7mm RM is built off the 338 WM case.
Highly recommend the 7mm Practical w/ 300 WM Long Brass
Supposedly Bertram is coming back out with it. The prior importer went OOB. I've heard RavensRock may be the new importer for their brass and 7WSM is one of them. I've got a 7WSM and love it. Also I have 250 pieces of Bertram brass along with 150 new Winchester brass. Not selling any of my brass. A 7WSM on a long action is money!!

I feel the McWhorter 7LPRC is one of the better designs. 300 prc necked down to 7mm. 300 prc is a better case than a 300 Win mag. IMHO

Don't know if this was already mentioned, but if you have a RUM 700, your only options are another RUM sized cartridge, RUM obviously, Nosler or another wildcat based on either of those.
PRC, Belted mag are going to put you into a feeding pickle if you try using them.
I like the 28 Nosler in a REM 700 with 3.7" mag length.
Cheers.

If you want to build a .284 cal because powder usage is an issue/concern, build a 7MM-08 or 7MM SAUM, but not with a RUM action. Again, as per my comment in #21.
I built a 7x300 win mag and you can definitely reach out a tag a deer or plains game animals in Africa. Love this round.
Amen Brother!
Jimmy if I had unlimited funds like you I'd build a 7mm practical or 7x300. I'd have to build it at 20 plus pounds though because I hate muzzle brakes.

I think it is so you cannot chamber 300 in a 7mm
Just ordered a suppressor yesterday. I had a chance to put one on my rifle and it sounds like a 22. It will be nice to shoot without wearing ear plugs or headphones.
10;4. Muzzle blast from most brakes is just too much for me. I start getting concussion symptoms. A Gentry or similar brake is about all I can handle.
