THis might be speculating but I bet 7x7 meant "right behing the shoulder in the lungs". BUt that is just my guess. As for your choices I think I would go with the winchester. But the rem sendero is a tack driver but heavy rifle. I like the winchester.
My own choice in a factory rifle would be the sendero.The ones I have shot have been more accurate than other factory rifles.I have no need or desire to have controlled round feeding.
Mnhunter-I have used push feed rifles for 30 years and have had no feeding problems so I don't need controlled round feeding.The one controlled round feeding rifle that I owned(parker hale 1100) would not feed single rounds dropped into the action.It would only feed rounds if they were loaded into the magazine.I find this inconvenient at the range where I always single load my rounds.Based on these experiences I do not require or desire controled round feeding rifles.
Remington or Winchester 300 ultra mag?
