This is my first rifle as I've been shooting handguns only for several years now. Well, I got 10/22 for my son and put a Bushnell Banner Dusk to Dawn 3-9x40 and it's a fun little rifle but I got the bug for big boy gun. Plan is for a "Sniper" rifle...but I'm not a sniper...so yeah most likely just 100+ yards at the range. As stated in the title it's a Rem 700 SPS Varmint in 308. I've narrowed the scopes to the following Nikon Prostaff 4-12x40 (Nikoplex) Nikon Monarch 4-16x42 (Mildot) Nikon Monarch 5-20x44 (Nikoplex) Are the Monarchs worth the extra money or is is overkill for this rifle? Will they really contribute to improved accuracy? Would it be better to save money on scope (go with Prostaff) and upgrade to stock to H-S or similar? I plan to bed and float the rifle so I think the better scope may be in order and I'd like the 20x magnification but I'm not sure if that's really significant over the 12x or 16x for 100-300 yards. Any advantage to the Mildot over the Nikoplex in a range situation? I prefer the clean look of the Nikoplex but using the Mildot to range targets or adjust elevation and windage without adjusting the scope sounds like it would be cool. Also any pointer on the best scope mounts would be great. I've seen videos for mounting including lapping the rings. Is that really necessary, what are the reasons for it? One last thing...plan to use a Harris 6-9" hinged bipod to shoot from the bench or prone. Any comments on this? Thanks in advance for your help!
