OK now that I've decided what kind of gun I'm getting (Remington 700 LSS in .300 win mag) I need to decide on my scope power. I've decided on the Nikon Buckmasters scope, which comes in 3-9 X 40 and 4.5-14 X 40. What I like about the 4.5-14 X 40 is that it has adjusment for parallax. Is this not as necessary with a 3-9? I want to be proficient out to 400 yds. Is the 3-9 powerful enough or would the 4.5-14 be more beneficial? Again, thanks in advance.
