DaveK Posted August 7, 2007 Report Share Posted August 7, 2007 Right, I've been reloading for years but this is the first time this has happened. Zero at 100 yards like I've always done with the bullet hitting 1" high. POI is cock on. I took it out to 150 yards expecting POI to be somewhere near perfect. WRONG. Right height but 2" to the left. Brought it right by 8 clicks and got it within the 2" target circle and was reasonably happy. Went out foxing last night, shot at two and missed them miserably. So the question is ...................... with my scope unexpectedly sending me to the left at 150 yards from zero at 100, is the scope lkely to be canted slightly? I'd have expected the bullet to go either high or low but maintan its windage setting. Dave Quote Link to comment Share on other sites More sharing options...
al4x Posted August 7, 2007 Report Share Posted August 7, 2007 What have you changed recently, or is it just trying some new re-loaded rounds? Quote Link to comment Share on other sites More sharing options...

DaveK Posted August 7, 2007 Author Report Share Posted August 7, 2007 Same reloads but different distances. I've always zeroed at 100 and wanted to try it out further for comparison. Warne rings and bases. Dave Quote Link to comment Share on other sites More sharing options...

Devilishdave Posted August 7, 2007 Report Share Posted August 7, 2007 The places I would look first are at the scope and mount then the barrel. If there is no wind and both groups you shoot at 100m and 150m respectively are good then you have a columation error meaning the alignement of the optical axis and the axis of the bore. Hopefully it is just somthing in the scope mount that has worked it's way loose. It might be a good excuse to spring for a custom barrel if your barrel is bent though. I would sugest that you look down the barrel with both eyes open if you see shadows in a cone shape going off to one side that would indicate a bent barrel. ensure thae barrel is imaculately cleen so you dont mistake a smear of dirt for a shadow. The alternative is check the scope and even if it apears tight strip the scope mounts and bases down clean all mateing surfaces and re assemble using loctite on all screws. Ensure that you have the same size of gap on either side of the scope clamps and ensure all screws are tight. Lets hope it is somthing simple and cheap.

Graham M Posted August 7, 2007 Report Share Posted August 7, 2007 Hi Dave. Sounds as though the scope isn’t plumb. This means that it will send your bullet to the centre of the target at 100yds but will continue to send it progressively further to the left as you get further away. G.M.

Devilishdave Posted August 7, 2007 Report Share Posted August 7, 2007 Fister you are quite right a bent barrel will shoot a bullet in a straight line and it wont curve as it flys. The point is if the scope is pointing straight ahead and the barrel is pointing (because it is bent)slightly to the left so to for instance be six inches off at 100m you can zero spot on at 100m but it will be further off at 150m by 9 inches which would be an aditional 3 inches. that is not an exact example but you get the idea. Remember the scope mounts to the action and not to the barrel Dave Quote Link to comment Share on other sites More sharing options...
henry d Posted August 7, 2007 Report Share Posted August 7, 2007 :( Mainly due to it being the simplest error to correct. Quote Link to comment Share on other sites More sharing options...
dunganick Posted August 7, 2007 Report Share Posted August 7, 2007 check cross hairs are actually straight in relation to the gun. Its very easy to have cross hairs wonky making you cant it. Quote Link to comment Share on other sites More sharing options...
markbivvy Posted August 7, 2007 Report Share Posted August 7, 2007 Went out foxing last night, shot at two and missed them miserably. So the question is ......................should i let the wife do all the shooting. yes mate. :( Quote Link to comment Share on other sites More sharing options...
mry716 Posted August 8, 2007 Report Share Posted August 8, 2007 99% of zero problems are down to the person shooting but the person shooting thinks 99% are down to anything but him/her. Some rifles shoot 'barrel shaped' trajectories and there is nothing you can do about it. ie ok at 100 1" off left / right at 200 but ok at 300. Just set zero for mid point if that is the case. If you have not dropped it taken it to pieces then it will almost certainly be down to you. like a cold it will be better tomorrow.

DaveK Posted August 8, 2007 Author Report Share Posted August 8, 2007 So last night I checked the rifle out in the back yard and found the scope canted left from bottom right to top left. minor adjustments and it seems to be on now. Dave. Bivvy, up yours !! :( Quote Link to comment Share on other sites More sharing options...
mry716 Posted August 8, 2007 Report Share Posted August 8, 2007 Wrong Dave. If its OK now it was ok before. Scopes dont move on their own. You should now be shooting to the other side. Re setting scope, I find the easiest way is to set a narrow 6" steel ruler on edge on the rear mount and then set the x hairs to that. Do check as you tighten as you can pull off line by quite a few degrees and find it is still not perfect. M Quote Link to comment Share on other sites More sharing options...
Dunkield Posted August 8, 2007 Report Share Posted August 8, 2007 I get the rifle level without a scope on it, using a small spirit level. Then stand a longer spirit level some way away, and get the vertical crosshair to lay up the side of that when looking through the scope.

Bazooka Joe Posted August 8, 2007 Report Share Posted August 8, 2007 I find the easy way is with a shot saver/coliminator, you can get your vertical line true on the crosshair. BJ. Quote Link to comment Share on other sites More sharing options...
DaveK Posted August 9, 2007 Author Report Share Posted August 9, 2007 For information the minor adjustments I made were to take the scope off and start again using a spirit level (which is now nailed to the scope) in several places on the rifle to make sure it was true. I then mounted and secured the scope. I'll be blasting away at 15 yards later today but again its cock on at 100. Dave Quote Link to comment Share on other sites More sharing options...

DaveK Posted August 12, 2007 Author Report Share Posted August 12, 2007 So how many of you can get a fox in to 15 yards before you shoot it? Must be sorted. I've taken a couple of foxes since at @ 150 - 200 yards. Las thing I saw lurking in the bushes Mark, was the Pudsey Pervert :blush: Quote Link to comment Share on other sites More sharing options...
