Woodlander Posted October 4, 2014 Report Share Posted October 4, 2014 Recently bought practically unused M595 .222 From a gunshop. Used a box of shells attempting to zero it,but couldn't get on the target. Borrowed a mates laser boresighter,tested 2 high end scopes with 2 high end mounts. One only zeroed on the laser point on the very last click on the windage turret,the other ran out of adjustment even before it zeroed. It would seem to me that the rails might be out of alignment. Has anyone come across this problem or heard of something similar. I have boresighted my rimfire and this zeroed practically centre of the adjustment range,so it seems to be a problem only with the Tikka. Any suggestions please? This was not a cheap rifle.

Beretta28g Posted October 4, 2014 Report Share Posted October 4, 2014 (edited) Tbh mounts are my first port of call. I have 2 Tikkas and find both zero with no problems. You can always swap the mounts round to help on windage adjustment and shim for verticle issues. Btw always make sure that the scope was optically centred before you try to zero. Edit Boresighting isn't the be all and end all. You cannot be truly zeros with a laser boresighter it's only to get you physically on to the target before you start firing live rounds.

welshwarrior Posted October 5, 2014 Report Share Posted October 5, 2014 What mounts are you using? Windage adjustable mounts may be an answer to the issue but be sure you have an issue first. Quote Link to comment Share on other sites More sharing options...
Woodlander Posted October 5, 2014 Author Report Share Posted October 5, 2014 I used Optilocks and Warne mounts. In the cold light of day and being as both zeros were very close to each other when I ran out of adjustment,I'm now suspecting a wonky boresighter. If the wind drops off a little today I'll attempt a few more shots on paper,opt ally centring scope first and starting off at 50 yards. Thanks fellows for your replys,I'll let you know how I get on.

Dekers Posted October 5, 2014 Report Share Posted October 5, 2014 Forget a boresighter, just get a zero target out and start with it at the end of you barrel if need be, then move the distance out steadily. See how you get on, make sure everything is tight, remove the mod if fitted and adjust scope as required as you move the distance out. I would be surprised if you don't get it sorted that way, or actually find what the problem may be. Quote Link to comment Share on other sites More sharing options...
dkj7176 Posted November 4, 2014 Report Share Posted November 4, 2014 If practically unused might mean uncleaned did you get a borescope ? Maybe bore is rusty? Quote Link to comment Share on other sites More sharing options...
joe soapy Posted November 4, 2014 Report Share Posted November 4, 2014 Center the scope, check all fittings for correctnes, fit scope, with bolt removed , clamp rifle in a workmate, sight through bore at a far distant point, mount scope, If the distant point does not coinside with crosshairs within say 20 clicks suspect something wrong with mounts or rail. Easy test for rail is to fit a scope previously zeroed on another rifle. rails on new guns should be exactly in line with bore. dont accept a new gun with problems, it will always bug you Quote Link to comment Share on other sites More sharing options...
Underdog Posted November 4, 2014 Report Share Posted November 4, 2014 Only one way to bore sight a bolt action rifle, bolt out and use your very own eye! U. Quote Link to comment Share on other sites More sharing options...
