Been on one sheep hunt as a packer... I carried a pack full of stuff for the hunt, and packed sheep out. I did pack the hunters Christiansen Arms carbon fiber everything rifle a good bit too. That was a sweet rifle. On my own goat hunt I used a Kimber Montana that was a particularly good shooter. That was a pretty sweet rifle too. I carried that rifle quite a bit hunting marmots here in CO, at elevations above timberline up to about 12500'. I ordered a NULA this week in .284. Going back to a light rifle.
