Thanks for the kind words, y'all. I'm happy to provide some entertainment.
I often see guys throwing ultra light builds together. Do you feel it would have made you a better hunter if you had a lighter rifle on this hunt?
Hmmmm, interesting question ... an ultra-light scoped rig to me is 6lbs. My set-up is 7lbs. So, I don't think that 1lb would have made a difference for me. But the difference between a 6-7lb rifle and a 9-10lb rifle is significant in my eyes. But, if you're carrying the rifle on your pack, then it can be treated as any other item in your pack if you are only trying to shave weight. You can get a 2lb tripod instead of a 4lb tripod, or shave a couple pounds from your tent/sleeping bag setup - lots of ways to shave weight in your pack that might be cheaper than shaving weight from your rifle.
That being said, I was carrying the rifle by a sling, and that was a big PITA (especially with a backpack, the dang sling doesn't want to stay on your shoulder). The guide didn't want us to leave the rifle on our packs in case we jumped an elk and only had seconds to react. At 7lbs, it feels super light compared to my other rifles.
So, sheep hunters, backpack hunting 10 miles from a road, in the wicked terrain they hunt, yeah, I might go for a 6lb rifle. Otherwise, I feel a 7-8lb rig is "ultra" light.
And all else equal, it is easier to shoot a heavier rifle - less perceived recoil, less chance you will flinch, easier to potentially spot hits in the scope. The 6.5CM is a pretty light recoiling round. I wouldn't want to practice much with a 6lb 300WinMag.
