Bolt face diameter's

If the cases are of the same parent case (25/06,280rem,270win,30/06,338/06,35 wheelen
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
a 300RUM.

Hope this helped

Thanks! That makes perfect sense.
