I too have a complete set of 40-70 SBN dies including a trim die which I have used for forming from 45 cal. brass. 45-70 brass can be used but will result in brass with too short of a neck. 45-90 brass works best. I use the trim die to get the dimensions close and then once formed all you need is a  Lyman 40 cal. M-die for neck sizing. I suspect that a 45-70 seating die can be used for pushing the bullet into the case. I would be happy to make some cases for you if you supply the 45 cal. brass and if you just pay the shipping. Forming the brass requires that it must be annealed before the forming process begins and then cut down to the correct dimensions. I then will run the cases thru the regular sizing die to get the final shape Depending on the brass and your chamber size you might need to ream the necks after you fire the brass one time.
