The first one you had a kink to the remington 700 extreme condition 2 in 7mm rem would be a fine rifle also the last one you have a link to in 7mm stw. That would be my choice out of the three you have links to. My 7mm rem is a ruger Mark 2. I absolutely love it, my nephews is a a wood stock 700 adl. Any remington 700 would be a good choice. The first one you have a link to is a nice rifle. I like the last one in 7 stw. But as a said earlier factory ammo is limited and can not be had at stores like Wal-Mart. The 7mm rem is a flat shooting hard hitting round. I have 13 rem 700, every one is a good shooter. Gunsmith like working on them and their is mainly extras and parts available for them. For scopes I mainly have leupold vx 1 3-9x40 in leupold bases and rings.
