That can only be answered correctly by keeping good records and monitering your ammunition, performance, and expected longevity.
Case in point, some ammo, in some guns, in certain atmospheric conditions may be more corrosive than others. And that's 3 variables with at least 25 possible entries a piece! General rule of thumb, unless you want to foul your barrel intentionally for accuracy, cleaning after every use is a good way to enforce inspection detail. Just my humble opinion

Even my 1947 .22lr is just as tight today as it was in 1947 (per records of my grandfather) . It is a very.... "in touch with history" feeling to keep guns multi generationally. Not only in body, but functional as well. I reckon this fall this old gal will bag a few squirells again. 75 years in a row across 3 shoulders. On the left. My son (he is 29) will get it next, hopefully he has my other 13 guns (2 yet to be bought) for years after I am long gone too. I posted the bore a few weeks ago in my post about bore scopes. Looks like new. Rifling and all

Made when they used real wood. Very nice 22.

Its true! But I am a fan of just about every gun. I like new fangled, and I like old fashioned. The only guns I don't like are one of two things...
Poorly accurate.
Poorly functional.
Only gun I ever sold was due to after a few shots on m855, it would send them further and further left as it warmed up. And I STILL regret getting rid of it instead of just swapping the upper.
