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.
