On my good rifles I have 50mm, 56mm, 60 mm objectives and 6X or so to 24X or so. They are also all Mil dot. As I try to shoot small things farther and farther away I can see the need for 8x-32 or 10x-40. I'm always up at near 24X Yes I'm over 50 and I just don't think that things are as clear as they used to be. I even have to put on reading glasses to see up close. So you guys that do long range varminting have you gone to higher powered scopes?
