RE: sighting in a 30-06
If all else fails. Remove the screws holding the simmons scope in place. Grasp the scope by the bell end. Slowly raise the scope over your head and behind your back. Now in one fluid motion throw that POS as far as you can onto a concrete driveway. Now retrieve said POS scope and throw the pieces in the trash. Head to your local retailer and check out Nikon, Leupold, Bushnell.... Buy a decent piece of glass. Nikon gives the most bang for the buck on the low end prices.
That simons scope is a weak point. At some point its going south. Most times its when athirty pointer is in the cross hairs. I wouldn't put a simmons scope on my no good brother in law from Illinios' rifle.[8D]
