GH Chamber and Chokes?

[Stepmac]

I think it is more uncommon to find a GH with original 2&3/4 inch chambers. I usually shoot RST 2.5 inch shells in my GH, but since it is a full and full I have been know to slip in some standard 12 gauge spreaders with no prob.

I read somewhere, maybe in these pages, that all SBT's have short chambers too. I shoot standard low base trap loads in mine.

Just bought a 16 gauge model 97 Win, made in 1910. I think that gun has short chambers too, but have yet to shoot it.

I have read Jack O'Conner's shotgun book about five times. In it he says that lots of folks shoot standard shells in 2.5 inch chambers. He admits to doing it without a second's thought. While I own a few new guns...a Browning Gold Fusion, an Ithaca 500, I prefer to shoot hundred year old guns. I have only lengthened the chamber on one old model 12 that is almost a century old. The rest I just shoot.
