Can do, but no sense reinventing the wheel. For starters it's hard to improve on Chuck Raithel's primer of a few years back. Like I said early in the other thread, I don't agree with all of it, but it's pretty darned good.
http://www.ssbpcrc.co.uk/Resources/Introduction%20to%20BPCR%20Loading.pdfI sent VA a brief synopsis of my loading procedure, and as soon as I can get my wife's assistance I'll post it here as an attachment. Haven't figured out how to do that myself yet.
Edited: See BPCR Basics thread.
I'm no guru on hunting ammo, but the general principle is to use a softer alloy, like 40/1, and a flat or blunt nosed bullet. Not a tight bore rider like the Creedmoor I mentioned earlier. The main difference otherwise boils down to tolerances; you don't want to have to push and jam to chamber a round when said tasty critter comes on the scene. Just as with modern rifles, tight usually produces optimal accuracy, but at the expense of easy loading of the rifle and repeat shots.
Those other factors you mentioned are really a matter of choice and what works best in a particular rifle. 20/1 or 30/1 alloy, depends. You get a bit more diameter with more tin. .030 or .060, fiber or LDPE (plastic) wads? Again, not critical. Compression can be important, but each load and rifle will have it's own preferences. The main thing with black is to make sure there is no air space between powder and bullet.
Sizing. I've never FL sized a straight case, even new brass, but there are those who do it every loading. I just neck size with an inexpensive Lyman neck die.
BTW, I use .45-70 dies to load my .45-90. Work fine for me, and a bit less expensive than buying dedicated .45-90 dies. I do use a Redding Competition seater, again a .45-70 although I believe Redding makes a special .45-90 version for Buffalo Arms.
There are others who post here who have lots of knowledge, and I'm sure they'd welcome questions as well.
I'd also suggest a new thread,
Black Powder Basics.
