More power can be nice, but realistically, I pull the trigger at 10x from 300meters all the way to 1200. I believe 12 is a great range. I have found on 10x, I can often catch my own bullet swirl off of my 308 (braked and 16.5lbs) and will often be able to make my own corrections.I used to think the magnification was where it was at, but after shooting a few matches, less is more when you have movers, agony snap. 12-16x is plenty for reading mirage for windage as well, I put an FFP 4-16 on my new Lapua for shots out to 1800m (if I can get there) I believe it will be more then enough. All this being said, it depends on what you will be using it for, are you shooting sniper/precision matches ever? how bout bench only? maybe F-class would be nice to have some magnification. I know you said no matches, but I guess your style of shooting will reflect what you need in the optic the most.
