Need help with my VXIII 2.5-8x36...

[eschafer]

A few years ago I mounted a vxIII on my 338 win... I sighted it in and had a good load developed shortly after... At least once a year I'll grab the rifle and go to my range... Each time, I must readjust zero.. Zero has now been readjusted 3 or four times with same proven ammo... Not until today, did I notice something that might be responsible... When I loosened the locknut for the diopter adjustment and while viewing through the scope, the reticle moved, significantly... Today I had to adjust the scope's turrets to raise POI 3" up and 1.25" left....

I have 2 other German scopes on other rifles, this has never come up.. Both are FFP, one a Schmidt&Bender and the other a Docter (both 1.5-6x42)...

Is a Leupold vxIII 2.5-8-36 SFP scope constructed such that diopter adjustment (focus reticle) affects POI... I know I have in the past adjusted reticle focus many times... I just assumed that such an adjustment had no effect on anything else... Or, do I have a faulty scope that needs to go back for repairs? Any help or knowledge on this subject is greatly appreciated..

I'd drop them a line:

Every time I've contacted those guys I've gotten a fast response. I've got that exact scope, but never had a problem with mine.

Yep...contact Leupold. They will make it right.

I have a VXIII 2.5-8x36 on my 375 H&H and have never had to adjust it from year to year. I'd get ahold of Leupold.

The VX-III's with Roman numerals were discontinued years ago. They've gone through at least 3 upgrades since then and have been using the Arabic numerals for quite some time. The newest version is the VX-3i. That is an OLD scope that is due for an overhaul or replacement. The rubber seals are usually only good for about 30 years in a scope. But Leupold will probably still honor the warranty and repair or replace it. On something that old it would also be a good idea to have all the rubber seals replaced while they have it. I'd talk to them about it
