I have nowhere near a million rounds fired. My best guess is 100,000+ on the trap field of which a little under 25% are registered targets. Maybe another 35-40,000 at skeet, a couple thousand sporting clays/5-stand and maybe another 25,000 at hunting waterfowl and upland? Of the guns I have owned many had more rounds through them than I put through them but my 101 is the one gun I own that has seen the most rounds by me personally and if I had to take a conservative stab at it I’d say its seen about 50,000 rounds probably 1/3 of which were heavy field loads and the remainder target loads on the clays ranges. Of the auto’s I’ve owned the 1100 Tournament trap saw the most action. It already had by the previous owners estimate 80,000 down the pipe when I acquired it from him and I probably put 20,000 through it by the time I sold it four years later. I am guessing it’s still out there somewhere? Seems to take alot to kill an 1100, mostly neglect. They all have their place but there is a reason those that have stood the test of time are still out there, some even being produced yet today. As for a value on the XL900 in question? In top shape I wouldn’t spend more than $250 but thats my opionion not necessarily a true value, only what I’d be willing to spend if I actually wanted one.
