Also, I'll save you a little trouble on loading 45/70 in case you don't already know.
They are like straight walled pistol cases. You have to make sure you flare the neck out enough before you try and seat a bullet. Also, a little vaselene on the sides of the bullet goes a long way with ensuring a 'crinkle free' load.
When I first started reloading I didn't have anyone to instruct me on 45/70 reloading, and I crinkled 5 or 6 brass before I found out what that expanding die feature was for.
