Those old reticles do break, sometimes. My rather over-large collection of classic scopes includes two with broken reticles.

However, my old FWB Sport had literally tens of thousands of pellets through it, sometimes hundreds in a day.

The trigger/safety went wrong twice and needed fixing. The breech lock up eventually wore until it was out of vertical alignment. The spring kinked and it and the piston seal were replaced with Terry Robb items (not a great choice). Field use wore the bluing. The stock developed a small crack at the pistol grip.

Basically, I wore that rifle out. Through use, not abuse.

But the Japanese ASI 4x40 I bought with it new in 1982 just kept soldiering on. Its only issue being that after about ten or fifteen years the front ring came loose and needed re-tightening.

My only Theoben rammer has a Leupold on it. Bomb-proof, and they fix it free if it breaks. I wouldn't myself chance a lesser scope on something which has such a sharp firing cycle. But many have done, without problems.
