A few years back, there was an article in The Double Gun Journal about a well used Nitro Special, that was used primarily as a waterfowl gun, with heavy loads, after it's owner used a sheet of .004 brass to tighten the gun up-he didn't affix the brass permanently, he was just careful when cleaning or dismantling the gun. It was left, loose, on the hook. I seem to remember the gun was used, hard, for several decades in that form. I think he sold the gun to someone who used it the same way, using the same shim.
I'm wondering if the guy in the video used too heavy a piece of shim, as he had to file on the breech end of the barrels to get the gun to close? Wouldn't it make more sense to smoke the shim itself, and work it down that way? Also, why the desire to make the shim permanent?
I'm all for inexpensive fixes for inexpensive guns, and maybe there is more than one way to skin a cat.
Best,
Ted
