A scope for 1,000 yard shot on range and 500 in the field, plus you are currently running a swaro?
You already know the answer, buy another swaro with turrets and be done with it. You are looking through excellent glass and are used to it. The only other option would be the high end Zeiss, not the cheaper conquests (sorry conquest guys/gals) or an S&B. You know what your eyes like, I sure know what mine like, I have a diavari on one gun, my primary, and Z6's on three others. The only three that have cheaper glass are a .243, a 6mm Remington and a muzzle loader. (Guess which ones don't get used very much)
That's a lot of elevation on that 300wm, 23.5 for 500 and 210.5 for 1,000 by my ballistic chart for a 180gr. norma bondstrike. Have fun. by the way, I'm zeroed at 300, 3" high at 100. I'm not a long range shooter.
