Chaps,
I bought a second hand scope with mounts for £15 which is great because I don't mind if I kill it trying to fix it. Anyhow the problem is the AO adjustment is way off which is particularly a problem at shot ranges where I cant get focus and PX at the same time. At longer ranges, when I adjust out PX fee at 45yds the scale reads 170yds. I'm guessing the cross hairs have moved due to use on a springer. Is there a book or web site I should read to learn how to fix this sort of thing?
Cheers,
Halam
