 Well I'll be.  They sure did and lots of times too.  And so did Remington with those sts shells.  No wonder I missed.
Sam, TPS has a whole chapter on chambers and bores. The answers to your questions are yes yes and yes.  I have a bunch from  1883 to 1910 and chamber size is not something I worry about.  Some I shoot at ducks with some heavy commercial loads , when I go duck hunting which is once a year or so to remind me about sitting in an icy blind and getting up at 4 am.
