The 1889 DOM DH 12 G "one " frame that i just received today has chambers that look like the photo above. When i slid in a rolled card to measure chambers, the card made a "hard stop" at that ring, instead of just binding to a stop as usual when measuring chamber length. So, that means my gun was designed for brass hulls? The depth to that "ridge" is 2 11/16ths. Thanks in advance for any info/ advise
