Seriously, Gun shooting moose with 45lb isn't your average guy....a good analogy, only experts shoot skeet with a .410, average guys use a 12 guage 😀
That said, though, OP, you obviously know moose and that's a big deal. You make a commitment to only shoot one when his eyes are rolled back and he's coming to your call so you need to shoot or he'll walk over you and that closeness will help. Just keep your wits and you know you can shoot a moose at 15 feet.....that makes a big difference with traditional bows.
My 2022 Alaskan bull wasn't huge, 50 inch rack and approximately 1300 lbs based on amount of boned meat. I shot him at 10 feet. Kind of like shooting an arrow into the side of a VW beetle on stilts. The big thing is just keeping your head together till the arrow is in him.
