Well I put a NIKON Buckmaster 3x9x40 on my Optima 50cal. I shot it at 95 steps and put my second bullet into the first ones hole, then the third was about 3/4 of an inch high/left, but all were in the bulls eye. For me that would be a long shot int places where I hunt. However the next time I shoot will be when I know if I am pleased with this scope. I could get my Tasco to shoot like that but it wouldnt stay on, so the next time I shoot I will know ifthe nikonstays on or not..
