Briman, although the Mauser 98's remain incredibly popular, there aren't many true controlled round rifles still produced, at least not by american manufacturers...Many are controlled round PUSH FEED rifles (hence the CRPF mentioned in my last post), which basically feeds like a controlled round rifle from the magazine, letting you cycle the action on your back if you wish, but they ALSO allow give up a little control in having a float/flex built in to allow you to drop a round in the chamber or open action and close the action with no damage to your gun.
The rifles you are talking about are the likes of winchesters and springfields. They are different from mausers in that they have a coned breach and have more play in the extractor to allow for it to snap over the cartridge rim. There is no difference otherwise in funcrtion betweeen them and a true crf like a mauser.
