Leupold fxii 2.5 power fail

[cajunchefray]

Going to agree with the others here and say there had to be some movement in the mount or rings to cause this failure.


Also, I had never heard of that particular model. I looked it up and saw it was a light weight model. Not sure that is the ideal choice for 460 wby.

The FX- 2.5 Leupold is a lightweight model, not necessarily "light" construction, but it is small, and the low mass is a benefit to the scope i.e. lower inertia than say a 3-9.
The lighter weight and inertia is a benefit on a heavy recoiling rifle, less stress on the internals.

Mr. Phil Shoemaker, Alaskan bear guide for decades, and a Vietnam combat veteran, has used the Leupold 2.5x for decades on a .458 Win Mag Mauser action.
That would be my choice for a heavy rifle, I have owned a couple. My only reason for changing is that, for my astigmatic eyes (that really suck), the FOV is a little tight for me. They eye relief is a big benefit for a heavy rifle.

Let us know when you get the rings, mounting and scope sorted out.

So I received the scope back from leupold with no issues and was actually 3 weeks faster than what was quoted for a return, I also purchased new rings from warne I opted for the fixed rings I stead of their quick detached version, I got the new scope and rings all mounted up just waiting for some time off from work so I can take it to the range and test it all out but after this post I have came to the conclusion that it was the rings is what caused the issue in the first place

Use a thin amount of liquid electric tape between the rings and scope. The thin paper Alaskan arms provides is a novelty. I like their rings and use them on 2 Rugers. One slipped on me shooting a 375 once. Fixed since then.

I have Alaska Arms rings on several Rugers up through 416 Ruger, and a CZ 458 Lott. All mounted with much heavier scopes. I have not had any issues with their rings. I have had a couple of issues with trueness of receiver machining.

I see that scope is a 2 piece tube type. Certainly a possibility that the tube threaded connection was not a good fit, and or a bit out of alignment also. Inducing its own stress.
The was a reason for the use-to-be heavily advertised one piece scope tubes.
