Wow.. well, I really don't know. I don't shoot competitively, at least nothing more than friendly competition with a group of gunning friends biannually. I've probably averaged around 150 rounds/year on doves for the last 4 years, and around 200/year on what clays I have played around with for the last 8(?) years... so there's 2,200... then there's squirrel, rabbits, quail, crows...
I'd guess somewhere in the neighborhood of 4-5,000 rounds over the 10 years I've had it. Again, nothing near what trap shooters will average, but quite a few rounds for a basic field pump gun. It's had minimal cleaning after each outing, only completely stripped and cleaned once, and no modifications of any sort. Like I said before - I'll buy another one eventually... it's my kinda gun.
