RE: 45/70 GOVT..
My most recent load is 52gr H335 and a Rem 405 jsp in winchester brass with cci 200 primers. I have to use the Lee factory crimp die to get an oal suitable for my 1895, but it's super accurate, and hits like a sledge hammer. I havn't choronagraphed any of them yet and frankly don't care too,as they are awsome on the muzzle and quiet rude at the butt.
