I have 4 coopers. M52 M54 M22 M22ML. All are accurate when you hit the right load. They will out shoot me every day of the week. The M92 is a different beast because of its weight. As Adam has said, to be accurate at longer ranges youneed to be a technicly sound shooter. I wont get into caliber...
Im in the area. Hunt 270 almost exclusively. Saw a few real nice deer last year, late. I may be able to help. I didnt draw. How many points did you have?
