Double Shotgun Firing only one Barrel
This shotgun came in with an unusual problem, that another gunsmith was unable to resolve. It was firing only 1 barrel and only occasionally. The hardest things to trouble shoot are problems that only occur occasionally. It can cause you to want to drink!!!
This particular Browning B SS 20 gauge, would occasionally fail to cock 1 of the barrels. This can be caused by a few different things, the gun being dirty is one of them. The first step in diagnosing a problem is a good thorough cleaning. Once all the old oil and grit is out of the action, we try it again and see if the problem resolved itself quite often it does. With this one however it did not. During the cleaning it was noticed that one of the screws was broke which allowed the receiver to wiggle when it should not wiggle, it was replaced. Additional, one of the firing pin holes was buggered up and interfered with the firing pins action. The hole was polished up and the dent removed which allows the pin to function as designed.
After these tweaks the shotgun still failed to function as designed. While looking it over I realized that the stock seemed to have horrendous fit, this being a Browning with an original stock the fit certainly was wrong. Upon closer inspection it turns out that over the years of hunting the recoil had “set” the stock back and it was no longer lined up the way it need to be. If left un fixed the recoil forces could eventually split the stock. The fix in this case is to re-bed the action into the stock using epoxy. The surgical tubing holds the stock tight in the position it needs to be in to distribute the recoil forces properly, while the epoxy material gets squished into the nooks and crannies that have worn into the wood over the years.
The pictures make this sort of repair seem easy, it is really not. You must have attention to detail, if you don’t do everything right you can end up with a stock that is glued to the receiver or parts in the action glued together. Or something as simple as dried epoxy wrecking the finish of the stock. As you can see I take every precaution, even masking around where the work is taking place.
When this sets up the stock will tighten down as it should and stay firmly in place no longer interfering with the hammer sears, the shotgun will function normally again and be more stable in between shots.
