I haven't had a lot of trouble finding hunting ammo; I have had to do some searching for reasonably priced ammo, however. In the past few months, I've taken advantage of Black Friday, Christmas, Daily Deals, etc., sales and secured a little over a thousand rounds of ammo. With reloading, it...
FYI...the original Ruger American Predator in 7mm-08 is a left-handed rifle. It's a solid shooter though; I got one for my brother-in-law and it shoots lights out! I liked it so much I was going to get one for myself and that's when I discovered it was a lefty only. The Gen2 is offered in 7mm-08.

Some PSA triggers have adjustment screws, but they're still not 2-stage quality.
Primary Arms has the Larue MBT-2S on sale right now. You might also check ALG Defense triggers.
Fords equipped with an external keypad will allow the doors to lock with a key inside the passenger compartment. I place a key fob in a Faraday bag so the vehicle won't detect it and hide the Faraday in the cab of my truck.
From your list, Nightforce would be my choice. They repeatedly track well and are pretty bulletproof.
I also like Meopta. Reasonably priced for a European scope, although their exposed turret selection is limited to a few in the Meotac/ZD lines. Good luck with your search.
