From an ad: "L.C. Smith 12 Gauge 2 Barrel Set. 28" vent-rib barrel chambered 2 3/4" and choked IC/M marked Ideal Grade. 2nd vent-rib barrel cut to 26 3/4" chambered 2 1/2" and choked CYL/CYL..." Looks like 2 1/2" 12g chambers could be special ordered but I'm going to take my chamber gauge by and measure for myself and will report back.
