I am looking for a cartridge to hunt big game out west and in Alaska. The largest game I hunt now are whitetail deer. I use a suppressed Tikka T3x in 6.5CM at ranges of 70-300 yards.

I am moving out west and want to go after elk, black bear, pronghorn, mountain goat, and other things. Later I plan to go to Alaska to hunt caribou and moose. I still don't expect to take shots at more than 500 yards. The 6.5CM should be enough for pronghorn but I think I need a more powerful cartridge for the rest.

I don't hand load. I don't put together custom rifles. And I am very adverse to recoil. So I am not even considering the 7PRC, or 300 Win Mag, or anything that kicks similarly hard. I cannot shoot those effectively. I am currently looking at the 6.8 Western, 7mm-08, or the 308. Which of those would be best for an off the shelf mountain rifle and ammunition? Whatever I go with will have my 8" suppressor on it. Are there other cartridges I should consider?

Your 6.5 is enough. Bullet choice is more important than caliber size. If you want “more”, I like the 6.5 PRC, it will have recoil close to the 308 shooting heavy bullets.

The 7-08 and 308 are not improvements over the 6.5 Creedmoor.

Do you want to change your thinking?

Watch EXO Eperience Project videos where they kill caribou and moose with 6mm Creedmoor. Then read the .223 for bear, moose, elk thread…

Buuutttt….he needs more down range wallop and knock down power!
 
Your 6.5 CM will be more than enough to get started out West for what you want to hunt. You don't need to start taking 500 yrd shots. Most of mine have been inside of 250. I prefer to hunt as close as I can. I recommend you spend the money you were thinking on a new gun towards optics. Start slow and build your hunt kit as you learn what you need through experience.

I used a 308 successfully on caribou while in the North Slope

There isn't a critter on your list that I wouldn't shoot confidently with a 6.5 CM. As mentioned, the 147 eldm is fantastic on game. I killed 2 elk from the same herd a couple months ago at 470yds and 515yds (different bullet, 156 berger) with a suppressed 6.5CM with zero drama and have seen multiple other elk, bear, deer, etc die quickly and cleanly with well placed shots from the 6.5.

You're all set!!
 
I think given you are all factory for a bit more velocity 6.5PRC would be the answer. Use the 156 Berger ammunition for the big stuff. The 147 ELDM for everything else.
