My trusty old 870? Who knows the round count. I am 53 years old and bought it at age 13. Paid $89 bucks for my Wingmaster NIB.
For 35 years it was the shotgun I had. Used it for dove, quail, ducks, geese, turkey, rabbit, squirrel, hogs, and coon. I suppose during each dove season I'd work through two cases of 500 so thats 35,000 right there just on dove.
Did not shoot all that much ducks and the other birds. But the rabbits and squirrels I hit pretty hard. Maybe another 25,000 on them.
I did use her for coon and hogs. The hogs got buckshot or slugs but I did not ever shoot all that much of it.
I did shoot some skeet and trap with it over the years till I bought my first O/U a few years ago. Probably just a case of 500 or a few more per year.
Old trusty is starting to show her age a little. Needs a blueing as the receiver is just about "in the white" now. The action is getting loose. But, I still trust her as my HD gun. I can disassemble and reasemble in the dark with my eyes closed and blind folded.
The 870 Wingmaster is an awesome weapon.
