Well, I finally got my 45-70 barrel (it's in the mail anyways) so I stopped by my local Cabelas today to pick up some reloading supplies among other things. I've now got W-W cases, 300 gr Hornady HP's, and RCBS dies. I didn't pick up any powder though in an effort to keep the total to a minimum (my wife was with). I've got a few powders on hand from the 45 Colt and 308 WIN. It looks like my IMR 3031 is going to work pretty well, I've got a bunch of BL-C(2) which appears to be a bit too slow, and I've got some Univeral Clays. I've seen a bunch of data for Unique in the 45-70 and Universal is very similar in all aspects. So, what is the consensus of using Univeral in the 45-70?
