RE: what is your opinion and why?
I have a Rifleman on my 270 7600, works very well. I think it really depends on your eyes. Any one of those scopes, with my eyes anyway, will take me right to legal shooting time, its the other features that sell me. What I really like about Leupolds is their non-critical eye relief. Theoretically, you should put your cheek in the same spot every time you put your gun up, but you know that theoretically gets thrown out of the window a lot of times when you are out hunting. If you are forced to shoot from an awkward position, you want to have the full field of view when you try to look through your scope no matter if your cheek is in exactly the right spot on the stock, this is why I like Leupold scopes.
