Hi,
If I optically centre my scope, and then at my zero range set windage by shimming the mount clamps will this cure crossover?
I have this on my bsa scoprion, sportsmatch 13mm mounts have helped over normal 11mm mounts but its still a bit off, If I zero at 30 yards I'm 1cm right at 12 yards.

The ox is slow, but the earth is patient.
Hmmm. I hear you, I wouldnt want to bugger it up.
But the theory is sound then?
I could try good old film negative, perhaps this would be more of a cushion than metal shims.

Look at the 14mm BSA adjustable mounts (Uttings website), might they improve things?sportsmatch 13mm mounts have helped over normal 11mm mounts but its still a bit off

Sportsmatch do a very nice one piece high fully adjustable mount. I'm getting one to cure my crossover problems.

Forth... I think they're made by BSquare, do you know if they'll take the BSquare riser posts?

Don't know, as the medium height mount I bought proved fine as it was, with a 40mm scope on my Superstar - but would be surprised if the BSquare risers wouldn't fit.Forth... I think they're made by BSquare, do you know if they'll take the BSquare riser posts?
Perhaps BSA themselves could confirm?

Sounds Ok as long as you are zero'd side to side at more than one distance in still conditions.
