On rifles that were accurate enough to tell,I never had a loopie go over 1500 rounds without issues.Most dont make it that far.
Seen it time and again.
The loopie erector will die in increments.
The scope itself will still function but have .3 to .6 of crap in the erector.
Sometime more.
Very commen.
Not something the 2 box of shells a year kinda guy would notice.

Only accurate rifles are interesting.
