I posed much of this in a similar thread awhile back, but since this helps me re-live my love of hunting, I'll paste it here as well. I have a deer lease with a well stocked travel trailer, so I will go over actual blind gear. In the 4x8 box blind, I have a small wooden box with a few bottled waters, toilet paper, a few rounds of .308 & .30-30, leather gloves (to use as shooting rests on the metal window frames, so as not to scratch the rifles), surgical gloves in case I shoot one too big to load by myself without parting it out, some inexpensive but surprisingly bright bushnell 12x50 binocs, bug repellant, and a quality LED flashlight.
For the evening hunts, I make sure to have a very bright mag light LED in the Sammy for tracking in the dark.
All I carry to the blind is the rifle, I-phone, leatherman waive, Gerber folder w/ gut hook, case stockman and zippo lighter in the pocket, plus an LED headlight if cloudy or moonless. Both my blinds are a couple of miles from camp, so I keep a 1992 Suzuki samurai parked there year round. I usually park a few hundred yards from the blind, and walk in quiet an hour before first light.
In the Sammy, I keep some "hard use" gloves for loading animals (they are always covered in cactus thorns here), some rope for dragging big boars to the boneyard, spare batteries for the game cams.
For guns, I have a marlin 336 w/ a 2.5x7x33 leupold for the shorter blind and for walking around, and this year I've been using a savage weather warrior .308 w/a bushnell elite 5x15x50 ao in a DNZ tactical base most often. I do rotate other guns a bit just to convince myself I need them, but the marlin and the savage are my two primary game getters.
If my son is in camp while I'm hunting, each of us has a long-range walkie-talkie. I like to hunt the mornings alone, and since he is allergic to both cold and 5am wake-ups, he's good with it.
With so many pigs this year, I've been wearing a 4" S&W 686 on my hip, loaded with hot 158gr Golddots, two spare speed loaders in the jacket pocket.
