I will soon be ordering the CZ 452 Varmint in .17hmr. I want to put a high powered scope on the rifle. I am really looking at the Simmons Prairie Master 6-24X50 Black/Mil Dot Scope for $70 at http://www.natchezss.com/. Is anyone familiar with this scope? If so, is it reliable and will it keep its zero (I'd hope so since the rifle is only a .17hmr)? Thank you.
