chicken and egg again

so IF indeed you are starting with a wild cat idea......a nearly standard cartridge,so again...if you make the reamer FIRST...then you can cut a insert chamber inside a solid metal .12ga sized rod/bank/insert and fire form to your hearts content,AND give same to recipient of rifle.
or keep them in bottom draw for whenever you need them....
it negates the need to fireform in die themselves but the insert will be eggzachary the same size as the chamber and the dies as all three will have been cut with same reamer.
hope that makes sence

@Micky Duck
no he is going to make his chamber reamer based on the die so that the dies he has available perfectly size the brass for the chamber.
it's a great idea

the thing is with Sammi specs is it's a spec, so it has a max and a min.
factory chambers are bigger towards the max spec factory ammo towards the min spec.
so that its a guaranteed fit no matter the brands or makers
dies are somewhere in the middle. as when we are reloading, we can adjust the tolerances to fit our rifle.
i think what akaroa is planning is one step further again making a custom reamer based on his dies so that the tolerances are super close so the dies don't need to work the brass as hard.
well, that's what if got from the idea anyway. clever bugger if he can pull it off.
