Am I out of my mind ? Today I just mounted a Bushnell elite 6500 2.5x16 x50MM onto my rifle. Last week I mounted my new IOR 2.5x10x42MM on another rifle. IOR is better then the 6500. Shooter next bench over had a 3.5x10x 40MM Leupold MK4 . That scope wilted in comparison to my 6500 elite. IOR made it look like the MK4 came out of a Cracker jacks box. Totally un impressed by the MK 4.
