I will be getting a CZ 452 Varmint in .17hmr shortly. I am still undecided about a scope. At www.midway.com, they have a Simmons Whitetail Classic 6.5-20X50AO for sale for $100. I own Simmons 8-point scopes and am content with the glass. Although my Leupold scope is built much better, I do not want to spend more than about $100 for a decent high power scope. So, is the Whitetail a good scope for my soon-to-be new rifle? Does the scope lose its point of impact when the magnification is adjusted and does it hold zero? Thank you.
