OK all, here's the million dollar question... what is the absolute best scope for under $500??? I looked into Millett, Falcon, Vortex, etc; even some Bushnells and Burris... NEED YOUR ADVICE!!!!!! REQUIREMENTS-Min 50mm Objective lens -Variable magnification with maximum magnification at least 15x -Horus reticle, or similar range finding reticle (MilDot & MOA Grad OK) -Turret graduation must be compatible with reticle. If MilDot Reticle then MilDot Clicks, got it? I don't care about color, finish, length, or anything like that so long as it gets the job done. This is an extreme distance predator hunting & range rifle in 300WM. We're talking 600 yds minimums Please give make & model with the approx price. Thanks!
