I need a better scope. Rifle is a varmint, target, paper puncher, and accuracy is paramount. With a budget of about $500, and a few requirements, 20x, give or take, and an adjustable objective. Thinking of a Leupold VX-II 6-18x, Nikon Monarchs 5-20x, Weaver T-series, etc. Is there a scope I have overlooked? I've Googled this to hell and back and still think there may be a hidden gem out there.
