I just bought a Impact Archery Cosmic sight yesterday i put it on my bow and its dead on at 35 yds as low as the sight goes. My bow a Parker Hunter Mag set at 53lbs with 350gr Carbon Express Line Jammers. I also have some Carbon Express CX200' s that weight 311grs with a 75gr tip do you have any advice how to fix this problem?? I moved the sight up and down it either shoots over or is 5 inches high at 30yds. My bow isn' t shooting that fast so i don' t know what the problem is. Do you think by adjusting my rest would make a difference???
