As a newbie to this forum, scopes (and my new RRA 308 Predator-HP), I had a few questions that I wanted to pose. First off, the intro articles on scopes are great and educational, thank you! Being new to scopes (this will be my first scope purchase), so please bear with me. I am looking at shooting in the 100-200 yd range for my scope needs. I am leaning between the Nikon P-308 (4-12x40 BDC 800) and the Bushnell Elite 3500 (3-9X50). Any thoughts? I am also completely open to other suggestions as well. Also, I am assuming from what I have read that I will need to use the RRA scope rings (regular, high rise, or cantilever). but not sure which one. I thank you for your input and sharing your thoughts on these topics with this newbie.
