Mine are too, but I took a deer at about 150yds with the shotgun last week and now I'm thinking I need something with better magnification.
Of course the length of this shot was the exception and not the standard but still.
I have a Leatherwood ML scope I bought for $120 or so. Glass isn't the clearest in the world, but I find the distance graduations are quite accurate for my CVA Optima using 2 777 Magnum pellets and a T/C shockwave sabot. Took a deer at 175 with my setup no problem.
