here's the ticket. kenton industries (google it). this is what I got for a 6mm Br; elevation knob, windage knob, check list & windage chart (only buy these one time). all about $200. knobs are $75 each and , get this, are marked in yards not lines that can't be remembered. ie; 200 yd zero then marked in 25 yd increments with at 300 to 800 yds. they will help you pick the style of knobs, just call, and you add the specs. this will give you a dedicated gun/scope/cartridge combo. the 14 power of your scope is just about perfect. past this info to others.
