A tight chamber and a die on the big side would make it possable. the other way around.....not so much.
Ok, you are saying that the fire-forming could have no sense, (making only the neck sizing, with the FL die unscrewd for about 1 turn), if the die "touch" (... and then resize ...) too much the body of the brass ?
.... HOW can i make the neck-sizing on the .270WSM ? .... The Lee Collet Die there isn't on the catalog ....
