Re: Leupold 3.5 -10x40 LR\T for long range shooting
Figure a 2" target at 250 yards is about .8 MOA wide. Reticle subtension on a mildot reticle is about .3 MOA. So you will be able to bisect it, but it will be getting small.
I've shot 4" clay birds at 500 yards with 10X, no problem. Same relative size through the scope.
If you are talking about a steady diet of targets that small, moving up in power isn't a bad idea.
