Scope Crossover

[robs5230]

Hi all well I've just put a new set of Sportsmatch mounts on the gun ( TO6C ) you know the proper one's for my R10 and I seem to have a bit of crossover bang on at 35yd but the near zero it is shooting left about 1/2"-3/4" any idea's how I correct it.....cheers

Hi Mick
I think Krisco was suggesting something other than crossover at fault.
If the mounts are sitting central above the breech (not canted), the scope is mounted straight and you are holding the rifle straight when shooting, I'd either suggest parallax error or clipping of silencer being the fault. What distance is your near zero ?

Here's a thread on the subject.

i was saying that perhaps you are just working around a problem. with messing around the scope and mounts.

you can try self centering bkl mounts, i bet it will still not shoot straight.

Well it shot ok with some crappy Hawke mounts that I doctored I would still be using them but they looked horrible

As oft explained (and you can explain to yourself using a piece of paper and a ruler) for all practical purposes crossover is mythical. Cant, on the other hand, is not. It's quite shocking, when first installing a spirit level to a gun, to note just how completely and utterly useless we are at judging the vertical when one's head is held at an angle wrapped around a stock - indeed, the vertical feels really "wrong".

Not to forget other things that may come into play like PX error, and zoom-wandering-zero error which can all conspire to change POI at different distances.

Hi Rob my near zero is 11.6 my far zero is 33yd the mounts are supposed to be for the R10 so their no cheap one's
