Practice helps that and if you find you are not that good at judgeing that get one of the levels mounted to the tube...But make sure its set to the reticle not the rifle, Siting a level on top will enter more error than the can't will, turrets are often not right, bit of shit on it, not holding it down right etc...been there tried that. Have scope levels but I rarely have to adjust the position, but i have on occation when in a rush.
    As has been said 2 subjects goin on here..

    For longer range the problem is dialing up a scope that is zeroed at 100 yards with a cant. This is why it matters at 1000yards as per terminators post.

    That article is about rig cant to ground...... not scope cant to rifle, the scope to rifle will remain paralell as long as the verticle wire of the scope is in line to gravity (plum to ground, verticle to gravity or how ever you like to explain it)...as soon as that is not the effects in that article come to play.

    Re the 10mm get a 50mm stick/wire (roughly the center of bore to center of scope on most rifles) and sit it on a level verticly and move the top 10mm out of plum...that will be what the reticle is like with the rifle verticle to get it 10mm out to the side...as long as the verticle wire is plum to gravity when firing. (Hard to put in words what I mean)


    With big flat stock buts and on benches with fixed rests the scope does have to be right to the stock as the rifle wont "lean" to correct the cant to ground...



    Most scopes are 50 odd mm above the refle to the center line.... get a 50mm stick and move the top 10mm and se how far out the cant on the rifle to scope would be.

    Oh and I must add if your lever is on the scope base like the one in the article your reticle wire will need to match it....

    My point has been about peoples ability to hold the vertical wire of the scope vertical to gravity.

    People are assuming that should someone mount their scope on the piss, they will/should be able to compensate perfectly for the scope to rifle discrepancy.

    After wasting ammo due to an epic bore sighting fail, I did manage to get my rifle zeroed pretty easily in the end (once I got it on paper). My main concern is having the scope adjustments doing what I want them to do. I don't do the LR thing yet, so whether I am out buy a few inches at 500m is irrelevant. In the past I've always just chucked it on and eye balled it, but would like things lined up properly from now on.

    Fair enough, the edge of the ply wood target board I use to sight in is fixed so it is perfectly plumb. I level my rifle and then adjust the scope to match the target board. A fence post or something driven in the the ground plumb would do the same thing for you if it makes it easier.

    I'm happy for now. Might have to try it with my other rifles and see what happens
