I am of the opinion people go with small sample experience to pick their hunting bullets.  I am prejudice toward full penetration with expansion, full caliber hole going in and double that going out.  I know the illogic of this view.  Nosler Partitions in rifles come close to my ideal.  In truth, deer go down with self defense loads as long as only the ribcage blocks the vitals.  I've gotten as many deer with the 45 ACP with JHPs as with a rifle when younger.  I don't hunt out west now, just woods hunt under 50 yards, not because of gun limitation but near dark, no time for a rest, and so on.  I only see deer in the open after the season.  I thought a doe was going to drink out of the horse trough a couple of days ago.  They must read the Tennessee game regulations.  I like the 41 Magnum as a deer round, Winchester Silvertip 175 grain.  I suspect the 10mm auto from my Glock G20SF will do just as well!

Too late for input to OP but here is my perspective.  Unless you are hunting with relative, brother or similar , nonresident requires licensed guide.  All that aside, moose have big lungs, unlike whitetails.  I have lung shots two 700 lb plus cows, elk and water buffalo.  My typical deer is shot behind the shoulder, with 20 yard dash being typical.  The cows just tried to stay with the herd, requiring multiple hard cast bullets.  The first cow was with a 44 Special, 240 grain SWC at 1000 fps from 4 inch S&W Model 24.  The second was with a Redhawk .45 Colt using RCBS #452-270-SAA at 1050 fps.  The second 44 special stopped under the skin on the left shoulder after angling forward from behind the right shoulder.  She did drop at the shot.  The second cow took four side to side lung shots before going down at about 40 yards from the first shot.  This isn't really too different from my limited bull elk reaction from a 308 Winchester or 35 Whelen for another cow elk.  Have a heavy rifle as backup, get close, keep shooting through the front of the chest, not just behind the shoulder like deer.  I would pick the 480 Ruger Super Redhawk with a red dot as my primary handgun and carry the Glock 20 with 200 grain hard cast bullets at 1200 fps as backup.  A .45 ACP with 230 grain hardball from a 1911 semiautomatic will kill a moose up close with neck shots, but not a first choice, more like a cow or me situation.
