Ok Ive been hunting for quite some time (27yrs+or-) but mostly bow hunting for the last 10. Bought a Remingon 700 in .300 WSM and want to set it up for semi-long range. Thinking about buying Leupold VX-3 LR 30mm 4.5x14x50 Boone and Crockett reticle and M1 Turrets installed to top it in classifieds here on Long Range Hunting. My questions are. 1. What is the benefit of having a BDC reticle AND M1 Turrets? 2. How would the M1 Turrets come into play? Would they be dialed in on the main crosshair if you wanted to exceed 500 yds or whatever the Leupold B&C reticle goes to? 3. Is this the right scope for the gun or am I going to cheap.? Budget is $1k or less. Advice and lessons appreciated.
