Pictured on top of one of my favorite books ever, is my "Redneck shotgun chamber depth gauge". Given that I am a thrifty person by nature, except that sometimes that has to go by the wayside when it comes to Parkers and other fine firearms, I am always looking for a thrifty solution to a problem.
I took a standard 2 3/4" 12 gauge shotgun shell and created a plug on the lathe, and inserted it into the 2 3/4" shell. In theory, it should work, except for I am unaware if the tolerances would be tight enough to always differentiate a shotgun rechambered for 2 3/4" versus one in its original 2 9/16" configuration. I don't currently have a known original shotgun with 2 9/16" chambers to try it on.
Here's the alternative:

With something like this, virtually free is better, provided it works!
While we are at it, how does rechambering a vintage Parker shotgun affect value? I would think with a "shooter" it would enhance value, but a high grade nearly mint gun it would hurt value. How about your standard VH grades with above average condition, or even a DHE?
