Confused 🤔
« on: May 24, 2021, 11:59:33 PM »
Alright guys and gals,splan (Ricky Recardo) to me why I can get my CV life scope to zero which has been on my liberty for about 2 years but can't get the new bushnell nitro same variable powers as the cv life 6-24 x50 to zero. It's a brand new scope with less than 20 shots. I need to do some more shooting with it tomorrow to be sure but this will be the second scope I've had problems with on my liberty. First one was a refurb so I guess that comes with the Territory. I do have to say, the optics are a lot better than the cv life but considering I only paid$30 for the cv life and over$200 for the bushnell the glass had better be better.

Have you optically centered the scope?  Are you using the same rings?

Start with checking the mount then optically centering the scope. If it is a new scope mount make sure that the mount is square to the breech. Beyond that, I got nuttin except for maybe gremlins

Perhaps you could "splain" what you have done and what you have not done and the distance at which you're trying to zero the scope.  Are you using the same mounts?  If using the original mounts have they been off the gun?  An incorrectly installed mount is a common issue preventing a scope from zeroing or sighting in properly.  Have you tried to optically or mechanically center the new scope?  New does not guarantee good.  Factory defects are possible.  Will the new scope perform properly on a different gun?  There is far more to the story than you're telling.

I'm not using the same rings. I'm using the rings that came on my utg 3-10x44 scope because the cheap scope is a 1 inch tube and the bushnell is a 30mm tube. The utg mounts worked just fine on my Aspen which is the setup I used to shoot the group in my avatar. As far as optical centered, I haven't moved the elevation and windage adjusters more than a turn. The windage was almost spot on when I first installed it and all I had to do was adj for slug drop at 40 yards. The last scope I tried on my liberty already had mounts mounted but like I said,it was a refurb. I guess I can check the optical center and see what that tells me.

Could be a myriad of causes. From what you've said so far, I'd bet on mounting issues or mount issues.  Bushnell glass is usually adequate, I've got a couple and they seem okay. Try optically centering the scope, redo the mounting, and start over. Remember that the hairs don't always move consistently when you first make adjustments, lots of guys tap the tube with a finger to help things along. If that doesn't help, you may want to try a different set of rings.
A trick I picked up years ago was to take my lapping rod and clamp it in the rings with the rings 'lightly' in the dovetail and then torquing the rings to the base / dovetail. Supposedly aligns the rings so little lapping is needed. Now, I generally try to use 1 piece scope mounts now and that solves the alignment problem, however, I haven't found a one piece 30mm mount for an 11mm dovetail yet.
Patience and careful work hopefully will solve your dilemma. Good luck.

Found out that tapping on the side of the scope would let it settle in to where I was trying to adjust to. I got it pretty close yesterday but ran out of day light and it's windy today 🤬🤬.  I just tap lightly on the side of the scope with the plastic prescription bottle I have my cast slugs in.

Tapping on the scope causes the reticle to move?  I would get a new scope!

I know many older guys that I have shot with swear by this "method" but there is nothing to settle in a scope.  With modern scopes this is something that will not make any difference, and if it does then you have more issues going on.

Do you have another scope that you know is good that you can try?

 One thing I have found with temperamental bargain scopes is that if I run them through the full range of adjustment , careful not to over extend usable ranges, they will come into and settle in and stay where you think you set them more reliably.
 With springers , a few shots do the tapping for you :)

From what I have been told about 'tapping' the scope after an adjustment is that the adjustment mechanism can be a bit 'sticky' and a 'tap or two' helps it move into place. I picked this up from benchresters using good equipment. I have read about folks doing it as well. I don't think it hurts, of course a little recoil should have the same effect..
Update on one piece mounts for 30mm to 11mm dovetail. Apparently the containers have come in and several versions are now available on fleabay and Amazon. Most are rather 'tactical', but a couple aren't and all are obviously chicom cnc work. I've got one ordered for a project.

I've been there myself.  I've had a Hawke Airmax 4-12-50 on my Liberty for a while now and constantly have to rezero due to poi shift.   I also had the same issue with a Discovery VT-R 4-16x42.  A couple of weeks ago, I purchased the DonnyFL Avenger Extender Adapter (fits perfectly on the Liberty), which actually tightened my groups up pretty significantly.  However, the POI shift was still prevalent. I recently removed the Hawke and replaced it with my Nikon Prostaff EFR, that has been reliable on my Ruger 10-22 and Gamo Urban.  No more POI shift and groups are as tight as ever.  So like yourself, I've had two scopes that wouldn't hold zero on the Liberty, while one works just fine.  All scopes are mounted using BKL rings.  Funny how that goes...albeit frustrating as helll.
