OK, I'll take whack at it. If it helps you at all, I'm a retired Gunplumber and I'm also somewhat opinionated (Yes, it's true) However:
I don't recommend running smokeless powder in pre-smokeless guns. Modern ammunition is loaded to SAMMI specs for pressure that will be safe in any gun originally chambered in your specified caliber. Just keep in mind .... the Pressure spike between smokeless and BP is quite DIFFERENT. Your '73 was designed around Black Powder. Use Black Powder. Also, remember, those folks from SAMMI aren't holding your rifle when it fires. Neither are those folks who will tell you "Hey, it's perfectly safe .. I do it in mine all the time."
Your '73 22 is pretty much OK for anything. The rifle was designed around much stouter ammunition and probably doesn't even know it's being fired.
Your Take Down '94 in 32 WS is pretty much the "Bank Vault" of lever guns. Was designed for early smokeless cartridges and can easily deal with much higher pressures than 32 WS can deliver. DO NOT shoot any form of "Round Nose" or pointy Nose ammunition in this rifle.
Loading advice is dirt cheap and worth what you pay for it. DO NOT accept load suggestions from ANYONE on a web page. Not even this one. PERIOD. Hot foot to your local Book store or Sporting Goods outlet large enough to carry a LARGE selection of reloading manuals. Look for the LARGE softcover book by Lyman. Read it until you can quote it from memory. Then to buy stuff. Oh, and most Sporting Goods store clerks know LESS than you do. Just ask for directions to the books.
