Title: Scope moved while shooting.
Post by: Cab on August 13, 2018, 03:10:23 PM: Just got my rifle all sighted in and then started noticing that I started shooting higher then normal while practicing later on. I checked my scope to see that it had shifted and moved backwards. Is this to blame on the rings? I know I didn't bump it or anything like that. I watched the guy install it at Sportsmans and it looked like he did everything correct for tension. I had the rifle sighted in and was practicing the last few weeks, maybe put 100 rounds through it and then noticed it shifted. any thoughts? just bummed that I have to get it all sighted back in again.

The scope physically moved, you can see where it was set and that it creeped back about 5mm.

Yea but I was nervous about them from the start. They are Vortex rings but their lower end rings at $20 and the reviews mentioned it here and there. Might be on me in this case.

Post by: Humptulips on August 13, 2018, 06:40:08 PM: A little loctite under the rings will help. Been through that about 40 years ago. I changed to weaver rings which are not expensive and have never had a problem with them.

Haha those are good ones too Jerry. Elkoholic was with me in Montana one year when I had the same problem you’re having. I had a pretty good set of rings by Burris and had loctite but they still worked loose! I am not a fan of 2 pics bases anymore, IMO one less thing to have fail with a one piece ;)

Is this a magnum round by chance?

Post by: Magnum_Willys on August 13, 2018, 07:20:58 PM: Switchin all to rail, nice be able to swap scopes, test scopes etc. blue loctite bases, green loctite under bases. I dont use loctite on quality rings, just bases.

:yeah:

If the scope shifted to the rear it wasn’t caused by recoil. If it was bounced on the butt pad the scope would shift to the rear though.

There are lots of simple tricks to hold a scope in place in any rings. Pull the scope off and use a little sandpaper to lightly rough up the inside of the rings. Put a thin layer of rubber cement iinside the rings before installing the scope. Apply a piece of scope tape to the inside of the rings. Clear nail polish around the scope rings after the scope is installed.

Or maybe the guy at the store just didn’t degrease the rings before he put the scope in there.

Do not skip the loctite, and make sure the setup is clean when you're installing.
