Thanks for the info, Mehavey. Right now I have a pair of El Patrons, a steel & brass cattleman and an 1875 Army Outlaw, all in .45 Colt. I plan on getting an 1873 rifle soon, probably in .44-40 but am considering other calibers.
The dies that they recommended at Bass Pro are the Hornady .45 Colt, series II, titanium nitride 3 die set. The salesman has been reloading .45 Colt for 30 years and says that's what he uses and wasn't aware of any difference in this set or cowboy dies.
I've saved your directions to a folder. I'm not to that point yet. Still have to order powder, cases, bullets and primers. I'll be doing that in the next week.
