My choice is none of the above.
Deer aren’t particularly hard to kill. All those loads will kill a deer, but are far over board and incredibly expensive.
A 255gr cast flat nose bullet at 1,150fps will shoot stem-to-stern through a whitetail deer. I’ve done it and seen others do it with my loads. (From rifle, equivalent to 875-900fps from handgun).
Important for accuracy with the Marlin is bullet fit as the bores tend to be over sized. Cast bullets may need to be .454” or even larger. Only experimenting with your rifle will tell what’s needed for accuracy.
My .45 is a Winchester Mod 94Legacy XTR with a 24” bbl. It has a nice tight bore and is splendidly accurate with most anything. However, to keep gasses from blowing back into action, loads need to be stepped up a bit over those for a SAA, or “Cowboy” loads.
One such load is the Lee 255gr FN over 8.2gr of Universal. Max for SAA Colts and clones/replicas is 7.8. Said load results in gas stinging my eyes and sooted cases and bullet lube in the reciever due to lack of case obturation. StarLine brass is the thickest and worse offender.
I like LongShot, Unique, and #2400.
Increased velocity only makes longer shots easier due to flatter trajectory. Power is adequate at lower speeds.
A marvelous accurate load is the Nosler max load for Ruger Revolvers with a 250gr Jacketed bullet.
20.0gr of #2400 (my measure throws 19.8) gives 1,750fps. My rifle shoots 1.5moa at 100yds with some Hornady “blems” I bought circa 2003. Bought 1,000. Still have most of them.
From your “choices”, I gather you’re not a reloader. That’s a shame as tremendous savings are to be had shooting bulk cast bullets, Those Buffalo Bore cast bullet loads using gaschecked cast bullets cost as much or more than quality jacketed bullet loads. Last time I priced some they were over $3.00 a pop. Mine cost about $0.15 a pop!
At present, whatever you can lay your hands on will probably work...
