A buddy of mine has the new Gen 3 Trigger Sticks that lock the legs at what angle you want. He bought a angled head for the screw on attachment and also uses it as his trekking pole.You are on a great start, here are my recommendations to your expenses/gear list:
Primos Trigger Sticks - I would either go with a non trigger stick bipod or a camera tripod instead of the trigger stick version (I had the trigger stick tripod and ditched it for a quality camera tripod + cheap cabelas bipod. If you have a spotter get a tripod, if you plan on just using binos get a bipod and save up for a tripod+spotter.
Vortex Bino Adaptor - Only necessary if you are glassing off a tripod. I would recommend the Outdoorsmans Adapter system instead. Additionally if you aren't after a trophy book buck, save the weight a just glass off your knees/offhand.
Badlands Mag Bino Case - Nice bino pouch, only critiques are its large n the magnetic closure can "snap" closed. I prefer the FHF harness.
Mystery Ranch Metcalf-Subalpine
Camp Chef Stove w/propane
5 degree sleeping bag & pad
Otterbox Venture 65 Cooler - Coleman Xtreme Marine 120 qt cooler (they cost $50 off the Big A website. I have a few and they are solid coolers)
Artice Ice Tundra 3x5lb ice packs - Half gallon milk jugs frozen + dry ice on the trip home with meat
2x 5gal water jugs - I would go at least two jugs and a case or two of bottled water depending on the unit and conditions.
2× 5gal gas cans
Additionally you mentioned a sat phone rental, I would check out a Garmin Inreach and the subscriptions they offer. Unless you need to physically speak to someone, the Inreach fits the bill imo.
I am in preparation for heading west this fall, my group will be chasing Antelope in early October out in WY. I am slowly starting to develop my packing list.
That's an awesome trip! That would have required a hell of a lot of cooler space if you would have bagged an elk as well.Did a similar WY mule/ deer antelope trip last year then drove to CO and hunted first rifle. I filled my WY tags but couldn’t close the deal in CO. 5300 miles on the Chevy by the time I got back to SC. I had a blast. I’ll do it again this year if I draw. Your 25-06 is about perfect IMO.
