Thank you Dave. Now we know that 4 unmolested Remington 12 gauge hammerless guns that were made for 2-5/8" shells, have chambers that measure 2-5/8" long. So why are Parker and Fox the only American gun makers I remember hearing about, that seemingly followed that "practice" of cutting 12 gauge chambers @ 2-5/8" long for 2-3/4" shells?
Food for thought gents.
