Scope. Centered over bore.
Been doing a lot of reading and YouTubing about yall target testing, and scope leveling. I have read that it’s ok to have a slight can’t on rifle, as long as scope is level.
It seems to me, in my basic knowledge, that it would be best to have the optic lined up straight over the bore left to right, and level. That it would produce better tall target tests, and help when getting out there real far. Everything I read says as long as it tests well, it will only affect it a couple inches at 1000. Is this something I need to worry about? Are there even products out there that take this into consideration, as it seems most rings and bases don’t allow for a lateral movement.

If the scope and barrel are moving vertically parallel to each other, then the scope doesn’t need to be dead center over the rifles bore.
Your over thinking it. Your biggest factor as to making a hit at 1000 yards is wind call. Making a poor wind call, will cause a miss by feet, not a couple of inches. |

most guys run a level on their scope. forget how the scope is mounted, what matters is how it sits while you are shooting |

S&K rings and conetrol rings are well made and are windage adjustable. I have S&K on my CZ 452 and sighted it in at 50 yards by adjusting the rings using allen nuts only, then You do elevation adjustments with scope. I love em ! I paid $155 for them a few years ago. There is nothing wrong with adjusting Your scope to Your bore.

Yes it's best the have the scope mounted directly over the bore. If it isn't your introducing some amount of horizontal angle. You won't notice it with a tall target test if the reticle is level on a canted gun. As long as the reticle is level the elevation will track straight up at any distance. Where it might be noticeable is in the windage at different distances. If the scope is offset left or right of the bore line the windage will be dead on at your sight in range. But, because there is a horizontal angle due to the offset, the sight line and bore line only Intersect at your sight in range and the depart from each other at closer or further distances. I think that the guys that are running a canted gun with a level reticle are doing so, with so little cant that it's really not even a measurable effect. Scope height, is a factor too. As scope height is increased, so does the offset from the center line of the bore, which increases the horizontal angle at any given amount of cant. It would be interesting to see a test with some extreme cant angles to see how much the windage changes from the sight in distance when firing at closer and more distant targets.

There is a good write up on this over on accurate shooter.
and conveniently there is a can't function in most ballistic apps. my rifle shows about a .1 mil change in elevation and .2 wind depending if it's left or right can't per degree. It's not much but when a 1-2 mph wind shift blows your round from one side of the 10 ring to the other. I don't need cant screwing me up on top of the wind. |
