Thanks everyone for the great feedback already! It's always good to read individual's experiences on here
way better than what I get off youtube and the gun magazines trying to make money. Of course there is no one right answer to what I'm looking for but it's nice to get real world experiences.
Unfortunately I know I'm looking into this sooner than I have the experience to justify doing it, but I'm sure most in here understand the itch to get another new toy. Currently my 6.5 PRC will be capable of hunting elk out to the distances I'm comfortable with, so it's hard to know what velocity/bullet weight I'll need down the road. I'm just hoping to be able to expand my capabilities.
For now I'll just continue to research and get more acquainted with the 6.5 PRC, and at the point I decide to get something new it sounds like I can't go wrong with any of the options mentioned.
