I just put a Bushnell Trophy 1.75x4x32 scope on my Ithaca Mod 37 Turkeyslayer and when I look thru the scope I can see the front bead/barrel in the lower half of the scope. Can't have that becasue I won't be able to see the entire bird. I put Millet 1" medium height rings on a Weaver 62 base. Are the rings to low? Do I need to go to the higher rings?
