This is the same thing I do. With the rifle locked down solid, Ive never had a scope tracking issue that didn't show up immediately when dialing up the scope's full range of elevation against a reticle projected against the plumb line on the wall.I will always check a new scope by projecting the reticle on the wall with a plumb line. Do this using a flashlight directed through the scope from the objective end, three feet from the wall. With the scope secured, you can check the reticle relationship to the turret using a level. You can also check the reticle’s s alignment with the plumb line by dialing elevation. The projected reticle should track with the plumb line.
I use this approach to:
Alignment the reticle to the centerline of the barrel, check action rail alignment, and plumb the scope, I have rarely if ever had to re-adjust my mounts for plumb when verifying by shooting a tall-test target. Scope bases are always bedded to the receiver, and depending on the type of rings, lapped for contact area with the scope tube.
I don't think so. I had made several shots before beginning the test. The barrel was warm, probably even hot. Going to try and take my time next time to watch this.Is it possible your rifle starts shooting right after it warms up? If I read your posts, it seems like you shoot 2 at 100 and then dial up with a slightly warmer barrel? Try starting your test at elevation and dial down. I saw a friend’s rifle do this consistently with his 3rd shot. 1.5” shift.....
I have noticed the same problem previously and found that, in my case, it was definitely attributable to the bottom of the cheek piece riding the rear v bag. When I switched the scope to a rifle with out the cheek piece, the scope passed the TTT with flying colors. I previously used my Bushnell bore scope and watched the perfectly aligned vertical crosshair slide straight up the borescope for 80 clicks and then right back down again. This lead me to investigate possible outside influences. I finally came up with the cheek piece solution. Not sure that you'll have the same exact solution but torque does occur when the bullet pass through the barrel and my first indication of the problem was a rifle scope always tilted to the right after recoil. Hope this helps! Oh! By the way; When I eliminated the problem, the horizontal dispersion of my groups was also significantly reduced.So I have a Leupold VX6 on my CA 6.5 PRC. Rifle shoots really well, I’ve got a load worked up that is consistent and I’m feeling good about this fall until the tall target test. When I dial up, I get a 1.5-2” shift to the right. I ran the test 4 times. Made sure the target was plumb with a level, used levels to mount the scope, and even tried rotating the scope counter clockwise (since the shift was to the right). Nothing has worked. No matter what I try, when I dial up, I get a POI shift to the right. I know there are a lot of things that can cause this. I’m using Talley one piece rings for the mount. I’ve remounted the scope twice. I’ve got a NF I’m going to put on it to see if it is the scope or the mounts, or the receiver. Anyone have any other suggestions? Would a bore sighting tool show the discrepancy?? I got the scope from Holland’s with his reticle in it. I’m going to call them on Monday to see what they have to say. Is it possible I just have a bad scope?? Thanks.
