Twicebarrel, you must be trying to open another can of worms with your outdated and unsafe guns with Damascus barrels comment, or are you just in the market to buy a couple of more ? I love it when the local gun store has them on the shelf for sale and marked " unsafe to shoot- wall hanger ". The price is always lower. All I shoot are Parkers and Remingtons with Damascus barrels and I can't remember ever checking a chamber length - just shoot my 2 3/4" reloads in them [ for the past 10yrs with no problems ].
