Trouble sighting in my Winchester 30-30
I have a new (to me) 30-30, from the five year gap where paperwork was lost. It has iron sights. I can't get it sighted in. It hits seriously high. I actually hit the paper today, but was aiming almost two feet low. The rear sight is as high as it will go. I even tried it very low just to make sure I wasn't being crazy. I just don't know what to do now.
Any tips?
TIA
