If you do much hunting in higher elevation for goats, sheep, etc, what is your rifle setup like? I've done a little bit of this hunting but want to do more before the mountains get too steep! I've owned Gunwerks and various carbon barreled guns but have never built one purposely for mountain hunts.
It all depends on your definition on mountain hunting. For me, it could be a mixed species hunt in BC where you might have a big black bear or moose opportunity while glassing for goats. That's a wide range of target weights and sizes and goats are notoriously tough to begin with. For that reason, I'm thinking bigger than my lightweight 6.5 PRC. That's a little lighter bullet than I would prefer for moose. Yes, you can kill moose with little bullets but you might only get an angle that needs as much bullet as you can put on it.
So I have a Christensen Arms 6.5 PRC that is light and accurate but again, the bullet weight is a little marginal for larger animals. I have a Gunwerks 300 PRC Nexus but the weight is 9.5# scoped. That's a little heavy for busting through nasty alders, etc. I'm thinking of something lighter in that 7mm to .300 caliber range and in a 20-22" barrel.
What are you using or what would you build for this application?
