Schmidt Rubin K312 scope mounting - bewilderment !

[kennyc]

Hmm, we're still baffled. Maybe it's because we have a small brain. Are we correct in thinking it may be because the scope isn't mounted parallel to the bore? A problem we have at the moment is that we can't zero the scope at 100 yards because we have run out of adjustment, and we can't shoot at 300 yards to check things out die to the ban on large calibres at Kingsbury.

you have a problem with either the scope or the mounts, the scope should easily zero at 100, reverse the mounts and see if the problem reverses.
