Sorry, when you add at least 2 zeros to that, then you have a reliable gun
Are you really making the argument that for a shotgun to be considered reliable, one must fire a minimum of 80,000 rounds through it?
Look, you know more about shotguns than I do, and I've always learned a lot from your posts, but that seems an order of magnitude beyond excessive.
I'd bet the number of people who put 80,000 rounds through a shotgun in their entire lives are a small fraction of a percentage.
Heck, I'd be willing to wager good money that no military or police shotgun currently in service has 80K rounds through it. Are you going to argue that all those Mossberg 590s, Rem 870s, Benelli M2s etc... haven't been proven?*
*yes, I know that many cops only shoot for quals, etc... but in terms of a minimum amount of ammo to shoot before considering a gun reliable, if they shot every single day for a whole year (no weekends, no vacations, a full 365 days), they'd need to put 219 rounds down range every single day to get to the point where you would argue the gun has proven itself.
