Some of the heavier stuff had log books for round life on the barrels and tubes. How would you keep track of the amount of rounds expended?
yeah, been there done that, signed off borescope and pullover gauge results for 81mm & 4.2" mortars in their logbooks. Worked with the guys who did the tank & arty 105s and 155s too.

No, we never tried to keep track of rounds fired in small arms, we had erosion gauges for checking serviceability.

No, what I'm looking for is if there was any kind of spec or requirement "gun must last XXXX rounds without major failure" type thing.

There may never have been one, I realize.
All else being equal (and it almost never is) bigger bullets tend to work better.
