Seasons greetings everyone, new to this board. I am looking to purchase a 6-24X50 scope (30mm) to mount on top my Weatherby Super Varmint 223 for general range and varmint shooting less than 500 yards. Have narrowed the choices to these 3 (all within about $100 of each other): 1. Burris Black diamond 6-24X50 ($700) 2. IOR Tactical 6-24X50 ($860) 3. Leupold Long Range 6.5-20X50 ($750) All have side focus, 30mm tube, 50 Obj. Mil-dot reticle. Please help me decide?
