I have purchased a new savage model 12 BVSS, 22-250. Most of my shots will be less than 300 yds but would like the capability to shoot 500. I am looking at the bushnell elite 4200 line. Just need some advice on magnifacation, at the high end is x16 enough or should I go up to the x24? Leaning toward the 40mm or would the extra money for the 50mm be worth it. Also any advice on base and rings for this set up. I am a skeet shooter and grew up shooting and still shoot rimfire. This is all new to me so any advice is welcome.
