If you assume that the chokes are going to erode (I'm not sure I buy it, given today's plastic shot cups, but...), isn't it logical to assume that the bores would erode also (altho perhaps to a lesser degree?). If so, then the choke deterioration would be less.

Is that the Michigan AuSable area TD- you are right Sir- there are no stupid questions on the DoubleGunShoppingNetwork, just stupid replies, and they don't get any stupider than ol' Homeless Joseph from Memphis-- he must have been the character sketch for old Tommy Hanks as "Forrest Dump"- 'stupid is as stupid does' I have, among other 12 bores, a M12 made in 1937 with at least 50,000 shells including steel loads through it, the bore mikes at factory, shines like a mirror and all the parts are original and when I hit the trigger is goes Bang every time. Also a Parker 12 live bird gun and a M12 Trap gun, easier to document by recorded number of birds, whether clays or with feathers, shot over the years- both guns have had close to 400,000 rounds through their respective barrels, still like from the factory--RWTF
