rossi_j 99 Posted January 30, 2011 Report Share Posted January 30, 2011 If the mounts are tight sounds to me like the the scope may be knackerd, I am no expert tho mate, obviously if it gets knocked ect that could be a cause, once zerod does it stay zerod for a whole session? this maybe a silly question but do you always zero at the same range? .atb. .ste.

davep1 0 Posted January 30, 2011 Author Report Share Posted January 30, 2011 its a new scope mate. can you over tighten the screws though? i zero it for around 35 but always start closer Quote Link to post
Marksman 934 Posted January 30, 2011 Report Share Posted January 30, 2011 have you made any changes to it??.....removed silencer/different pellets?? what rifle do you have mate? How are you transporting it to your permissions?? Have you overtightened the mounts and crushed the tube? Quote Link to post
Sweeney-Todd 208 Posted January 30, 2011 Report Share Posted January 30, 2011 Hiya Dave. Think I would be inclined to try a different scope, just to eliminate any possible damage to the one you have buddy. Bill. P.S. If it is knackered and you need another scope....I have a 4 month old MTC Viper 4-16x50 SF IR for sale Quote Link to post
pianoman 3,584 Posted January 30, 2011 Report Share Posted January 30, 2011 Sounds like the scope's very faulty if the rifle's new. You can very easily overtighten Allen screw scopemounts and crush the scope tube out of line. The only possible cure is to set the scope as truly centred as you can in the mounts on the rifle and "Anchor" the scope by cementing it into the leading or front mount with a strong Arraldite epoxy adhesive. This is a measure to combat scope-swivel or rotation in the mounts on rifles with a heavy snap-recoil. It works fine and keeps the scope in place and makes accurate zeroing easy. Being cemented to the front mount enables you to keep the scope centred while the rear mount is loostened to adjust the eye-relief. The downside is the anchored scope will be permanently set to that one rifle and will probably appear to cant over, off-true centre when mounted to another gun. In this case, it may help keep a possibly deformed scope in enough of a line-true within its sphere of adjustable zero and help keep accuracy. Either this or the waste bin I fear.
