Hey there rimfire shooters,
Well, IMHO some centerfire scopes can be a big problem. Now I don't know if this has to do with price/quality or just the scope I tried.
However, I bought a used 77/22 which had a cheaper Bushnell mounted on it and YES, PARALAX WAS A BIG PROBLEM.
I set the rifle up on the kitchen table and sighted at an object probably 50 - 60 yds. distant. With the Bushnell, ANY head movement or change of position caused the crosshairs to move.
I changed to a 2x7 Leupold - centerfire scope - and no more problem as far as my eyes could see. I mounted a 2x7 compact Leupold on the same rifle at a later date and again no problem.
My current Clark Custom 77/22 wears a 3x9 EFR Leupold.
Keep em coming! :wink:
