No one likes controlled round guns, and most guys that buy them screw them up by dropping rounds in the chamber. It might be possible that a CRFP action could handle it, but I'm not certain, it's pretty hard to get a basketball to pick a direction without spinning.
All you need is for the magazine to hold the rounds close to the chamber. You could have a bolt that is a foot long and it wouldn't matter so long as that when the bolt face contacts the rim, the bullet is starting up the feedramp.
1911s are controlled feed system- they don't have a rotating claw like a mauser 98 type rifle, but the rim of the cartridge must slide up under the clawlike extractor on a 1911 in a very similar fasion as with a mauser 98. A controlled feed system is what you almost absolutely need for this setup in a rifle, and the last time I checked, controlled feed rifles are still pretty popular.
