cherokee75,
I used to have a 1895 22" 45/70 and I would suggest you look at gunbroker for the purchase of brass. I was amazed at how much cheaper it was to pick up hundreds of once fired used brass online for about half the price than new brass, if not better. I just wanted to tell you that little tid bit in case you're interested. If I ever got another 45/70, I know I get my brass there.
