Like Darryl, I don't like alot of lines and stuff which can "hide" my target. I like a fine crosshair duplex. A dot would be a great second choice. Be careful of heavy duplex crosshairs as they will cover too much of your target at long range. I am also looking into the Burris Electro dot which they put into their hunting scopes. Would be a help in low light, dark background conditions. Mil dot reticle are a great alternative too (not cluttered as other reticles and can help in quick adjustments in aiming).
As to scopes, I let my budget decide. Scopes like the Nightforce are very good but muchos bucks. I lean towards the Bausch and Lomb 4000/4200series and most on this site will use Leupolds. IOR is getting popular and well priced for the features.
I personally LR hunt with my 6X24 Elite 4000 scope. I shim the scope (Burris sig rings)and base so that I have the full amount of elevation to use. There is only 26min of adjustment so shimming is a given. With most magnums, you only need 20 to 24min to get from 100yds to 1000yds. I set my scopes up with a 200yd zero and have had no problem dialing up to 1000yds. Excellent and repeatable knobs, very good optics and well priced. The other members of this product line have higher amounts of adjustment.
I also have experience with the "Tasco" super snipers from SWFA. I love my 10X for its repeatability, ruggedness, and amount of adjustment. Optics are good but not perfect. For the money, they are the best scope with over 100min of adjustment.
The next best is the new Elite 3200 10X. Very good design, compact, light, very nice mil dot reticle, pretty good optics. With about 80 min of elev. adj and under $200 retail, a great entry level scope. Mine doesn't move 1/4 MOA clicks but it is consistent and repeatable.
