I'd be alright if a sheep hunter showed up with either of those. If it were me I'd take #1 or maybe #4. If a hunter showed up with #4 I'd be nervous about his ability to shoot it well. The scopes especially the 6x18 would give me a case of the vapors.
I had a sheep hunter (wyoming bighorn sheep) show up with an unmentioned Muzzleloader. Ended up taking a nice sheep on the first day, but I was pretty nervous about it.
I would not carry the rifle broken down in the pack.
