Can't help with hunting gloves. You probably want mittens for added warmth. Mittens are almost always warmer than equivalent gloves, and they do make hunting mittens with quick releases or whatever for when a critter wanders by.
I wear these up here, but being gloves they aren't designed for sitting still for hours at a time in cold weather:

Waterproof, windproof, and warm as gloves go, though. They're good for about an hour in <20 degree weather before I start wishing I'd brought mittens. On the other hand, they're much more useful than mittens when I actually do stuff.
I tested three different sets of gloves by bringing them home and wearing them under tap water for a couple minutes, only those OR Aretes were truly waterproof.
Whatever you end up getting, make sure you do that water test, it's very telling.
