I think he meant the action itself.
No experience with the 700’s but the M70’s for a Rem Mag and Win Mag fed the 375 Ruger cases like they were made for them.
I’d almost think a RUM based might be too big between the feed rails but I have no first hand info about them. Remington 700's will handle/feed just about any cartridge imaginable. I was NOT responding to that, but whether the bigger cartridges wpuld provide any other advantage over the 7mm PRC. Once did an experiment with a .30-06 Remington 700, filling the magazine with a .30-40 Krag, .300 WSM and a .308 Winchester. They all fed well perfectly--though they obviously didn't enter the chamber. But the front end/ bullet did. Also ran the same experiment with a .338 Winchester Magnum custom rifle built on an FN Mauser action--and the .375 Rugers fed fine. My point is that a LOT of people assume that 700s won't feed "correctly" with various cartridges, especially compared to CRF actions. But the opposite is true. As a result my response was partly due to the question of whether the other rounds provide any "advantage." Which I assumed from the way he wrote the question that he was asking about "killing power," since the other cartridges he listed are "more powerful" than the 7mm PRC. I have taken (and seen other people take) a bunch of big game with all those rounds, and have yet to see a consistent difference in "killing power," as long as a good bullet in the right place.

Might also add that the biggest "advantage" any of those cartridges might have these days is the availability of brass and ammo.

My 7 PRC that is being spun up as I write this, is being built on Defiance LA Mag - not a RUM. We'll see how it feeds in a month or so. FWIW, my 300 PRC is built on a Rem 700 RUM action. Can't say one way or another whether the RUM action (ala a little bit different feed rail configuration) was/is actually needed - it's what I had available as a donor at the time. With the receiver cut for a Wyatt's extended box and follower, and the same installed, it feeds fine.
I never thought I'd grow up to be a grumpy old man, but I did, and I'm killin' it.

John, I took his question to mean which M700 would be a better donor rifle for the PRC (Win Mag/Rem Mag vs a RUM).

I have a big RUM LA Defiance myself that I have sorta talked myself into doing in a 338 RUM. I have had the action for about 9 months and changed my mind about 3-4 times since then
