With your 308 pistol I would go with a scope. Like mentioned above the red dot takes up too much space at longer distances. I've hunted with a T/C Contender in 7-30 Waters for years and it had a Burris 2-7 on it. The only timeI used the 7x was on the range. All the deer I took with that combo the scope was on 2x and that was more than enough. I did have a multi reticle "red dot" on my S&W29 that saw a couple seasons but put the open sights back on it. The only gun I have a red dot type sight on now is my turkey gun.
