ETC they will work.
Some cases have a rebated rim that could be the same rim dia. but have larger case bodies
and some of the rimed cases are the same as the 30/06 but the bodies are smaller.
Any of the 30/06 based case actions will work for each other with out any action or bolt work.
For example= the 300RUM has a magnum bolt face .534'' but the body is larger than most
magnum cartriges so you would have to open the rails a little if going from a 300win to
Hope this helped
