Cant Zero In Scope Help Needed

[archiekale 427]

make sure everything is tight on the gun the screws which old the action in this day and age you should not be shimming scopes make sure you have the proper mounts on the gun 25mm scope 25mm mounts or 30 mm scope 30mm mounts you will be suprised how many try to fit the wrong mounts if you are shooting and getting good grouping ( alltogether ) although still low you may have the wrong mounts on .the bullet may be be cliping the moderator try it without see if that makes any difference hope this helps

Never use a scope with turret adjusted all the way to the extreme of movement. Do a bit of research on how a scope works mechanically and you will understand why.

 

Start by setting both turrets to their mid point by winding gently to one extreme, count the clicks as you wind it to the other extreme and then wind it by half as many clicks back to the middle.

 

The scope is now mechanically centred which is a good starting point.

 

Now at, say, 15 yards (closer if you want to) shoot at a big cross marked on a large piece of paper or the side of a big cardboard box, not an X but more of a crucifix with a long vertical line. One shot is enough. Hopefully you will hit the paper somewhere! If not, move closer and try again.

 

Don't adjust the vertical turret yet. The bullet may land very high or very low but let's get horizontal sorted approximately first.

 

Assuming the mounts and the rifle are all "straight", you should not require much horizontal adjustment to bring the bullet reasonably close (within an inch or two) to the vertical line by turning the horizontal turret. If it is way off horizontally there may be other issues. Hopefully you will be ok horizontally.

 

If you are a long way off vertically, several inches, use shims to pack the scope to try and get nearer the centre of the target without adjusting the vertical turret.

 

Useful shim material is old photographic negatives or (my preference) a piece of steel or aluminium cut from the side of a fizzy drink can, it cuts easily with scissors. Cut the shim to about 4 x 2 cm and trim it to fit neatly inside the bottom half of the scope mount so the scope sits comfortably and slightly raised in the mount. Shim the rear mount if you want to raise the point of impact of the bullet on the target or the front mount if you want to shoot lower (I think I have got that right?). One thickness of shim is probably enough but use two if you need to.

 

Ignore anyone who tells you that shimming is bad or that it will damage your scope. We cannot all afford expensive adjustable mounts and shims have been used for decades. A lot of the more expensive scopes have very limited turret adjustment and require shimming.

 

Now fire another shot at the target and hopefully you will be within a couple of inches of the aim point. Fire a few more shots to make sure that you are getting a tight group. If you are not, then you have other issues. If it is a good group then adjust the turrets to get more or less on target and then move back to, say 30 yards and adjust, then 50 yards or whatever you decide is your zeroing distance.

 

At the end of all this you should be shooting with your turrets adjusted well within their range and a scope with erector springs able to do their job.

 

Unfortunately there are many variables and only if everything is right will you shoot accurately every time but I hope this helps a bit.
