I spun the needle again and came up with a few new things for me to think about. I had prviously only measured the 26" barrel chambers. Thought they would all be the same. I am using Brownell Chamber gauges which seem to produce very accurate measurements for me in the past. From the pictures you will see the 26" are truley 2 1/2 inch chambers. The 30" barrels on the other hand are 2 5/8 inch. Also just for info the 30" are the barrels marked 1 and the 26" are marked 2. The 26 inch barrels appear to have been shot the most.
