I bought a Ruger Frontier a few years ago, in .308. Added a Leupold 2 1/2 "Scout Style" scope. I love the set up. My concept is to practice, a lot, with it, and when you have to get a quick shot, it should, by then, be just throw the gun up and it will be near automatic to center crosshairs on target and shoot. You don't even need live ammo for a lot of that practice time. Just need the practice of getting that far relief scope on target, ASAP.
Shoot with a friend and at his range, there is a gong (was a gong) at 100 yards. It was probably like 8" dia., or so. We would stand there, off hand, and shoot at that gong, over and over. Amazing how fast a guy could get with that set up and hit that gong, off hand, repeatedly.
With that being said, after I bought the gun, I decided to go archery for Blacktail deer, and have not used the gun hunting, yet.
Ruger no longer makes the Frontier, but I am debating on getting another in .243 or 7mm-.08 for the wife.
