Default Can old 3x9 scopes 'lose' their 9?....

So... I got two rifles with older scopes made probably in the late 1970's-early '80s.

One shot great at any magnification for years... up until last year. It's deadly accurate at 6x, but seems to wander at 9x when shooting out to 200 and beyond ( never used to do that).

The other... is spot on accurate when dialed in at 5-6x at 100 or 200 yards.... if I crank it to 9.... it's on paper but all over at 100.... barely hits paper at 200.

So... naturally, I'm treating them as 'fixed' 6x scopes for hunting.

They are backup rifles anyways.

Can this actually happen? Or am I sniffing too much locktight?

And yes... I should know more about scopes, but I've only been hunting using scopes for maybe 7 years now out of my 35 years hunting.

Yes they can. Those old seals, gaskets and sealing compounds usually dry up over time and cause issues. The newer, better materials not so much .

Get a trusted shooter to try your set up. Then you might know for sure?

I had a 35 year old leupold 3.5 X 10 that went wonky this summer. It was still zeroed at 3.5 power but turn it to 10 and everything got very blurry. Any thing you saw through the blur you couldn't hit. Sent it to Korth back in 8 days.

This exact thing happened to me with an old Banner quite a few years ago. Took me a while to figure out why I kept missing. At around 6x you could see the crosshairs jumping all over the place if you cranked the power up or down when looking through the scope. Also a change in direction when Turing the power ring would cause the crosshairs to jump or if you rapped it on the side.

Bottom line is that scope was dickered and I threw it in the garbage, you should probably do the same.

Time catches up with all of us, even scopes. If they happen to be Leupolds send them in.
