I have recently starting getting more serious with my lr shooting, so I went and bought me a 700 varmint in 308 a couple weeks ago. The first thing I did was ordered a nightforce 20 moa mount to try to get started in the right direction. I'm now looking for a scope in the $700 or less range, i want it to be about 15-24 power on the high side, spans preferably side focus. I've found a Bushnell elite 6500 2.5-16x50 for $650. Is that the scope I need? Or is there a better option for me. Thanks
