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?
