7mm stw on a 700 action, dont have a clue about it other than it's definitely in need of a scope, no markings on the barrel at all so we have no ideal what kind it is.
7STW will reach waaaaaay out there and touch one. We used to shoot one back in the day, but then we realized we had waaaay too much gun for the 75 yard shots we routinely took in the thickets we hunted.
