Thread: Scope cant?

    Default Scope cant?

    This is regarding my scope on my HW97K.

    If I set my scope in zero at 22m, when I shoot at 10m I shoot low (which is to be expected) but I also shoot about 10mm right.

    Is this perhaps because the line of sight is not directly vertically above the line of fire, or because the scope is canted?

    I set my scope up by putting a spirit level across the stock at the rear of the receiver, and then sighted in on a plumb line to get the cross-hair vertical. When I had the stock off the other day I noticed that the top of the stock is not perfectly flat all around, which leads me to think that perhaps my spirit level method was not accurate.

    Any thoughts from others that may have experienced this?

    Sounds like your scope is not in line with the bore.Like Sniper said check your mounts.

    I agree, check your mounts. An easy way to detremine if your scope and bore axis are not lined up is to zero you rifle at 20m. Shoot at 10m and then at 30m. If your POI is to the right at 10m and to the left at 30m your scope axis is not inline with your bore axis.

    If your scope cants to one side you will find more than likely that your POI will string out to one side only and also shoot lower than a perfectly fitted scope

    I can see how Francois post makes sense, and I believe this may be the problem, but other than putting on new mounts is there any other way of sorting this like, for instance, putting one of the mounts on so that the fastening screws are on the opposite side?

    You might resolve the problem by swinging the mounts around as you suggest. Chances are that you may get the fitting right by doing just that. Another way of doing it is to shim the mounts, but it all depends on how tight your dovetail fit is and it is a bit tricky. You need very thin shimming material, .001" - .002" at a time. Try to swing the mounts first. Good luck.

    To be perfectly honest the only sure way to stop this is to use a new set of mounts. My recommendation would be to go for a set of BKL double strap 30mm rings - expensive but worth it in the long run.

    To check the alignment of the scope in relation with the barrel:
    Insert a strait edge in the rings. With 25mm rings I used a fluorescent tube clamped in the rings.
    Now check from front looking into the barrel and see if the barrel and the tube are in line. Repeat from the back and also get some body else to double check with you. Hope this is explained clear enough.

    Allan,

    Only a few years ago you could not buy them in the UK, you had to direct import them from the USA.

    BKL will sell direct over the net, also didn't importer get some in recently?

    If you create demand for these items someone will import them, just look at boondock and the zos scopes.

    Some people might recoil (pardon the pun) at the cost of these mounts, but I can't fathom the thinking where people spend a lot of money on the rifle and scope then try and skimp on the mounts - they are a vital link in the chain, essential to accurate and consistent performance.

    I got a mate of mine in UK to buy me a set of Accushot mounts off JSR website, they should be posting them to me this week I hope. At least with them I won't need to use the Gamo scope stop and I can space the rings out properly.

    On the HW97K, it is possible for the rear of the scope rail to be misaligned with the front of the scop rail, due to the rear of the rail not being on the receiver tube, but on the block that unscrews which houses the trigger.

    Does this ever work its way loose over time, resulting in scope alignment problems?

    [html] No, one of the bolts in front of the trigger housing screws into both tubes. Unless that bolt falls out, they will always be alligned.

    Let me rephrase that. The bolt in front of the trigger guard, goes through the first tube and screws into the inner tube in the thread section of the two tubes.

    Makes more sense? Maybe not..<img src="/e107_images/emotes/default/crazy.gif" style="border: 0px" alt="crazy.gif" /> [/html]
