The problem is that I sent the gun to Simmons in the first place.
I have had this gun since 1960. It has been used moderately but never abused. I had not shot it much in recent years, not because of any problems with it but I have an LC Smith or two that are my 'go to' guns any more. They fit me so darn well that I have a hard time picking anything else up.
Anyway, I decided to have rib put on the Sweet Sixteen. I was never a fan of that lump of a sight that Browning tacks to the end of their barrels. Simmons did a good job on the rib but as you probably know the heat discolors the barrel and it has to be re-blued and then it doesn't match the receiver so that has to be re-blued. Oh, they also jeweled the bolt and loading agte ( which I was not pleased about and did not ask for).
When the gun came home I took it the the skeet range and within the first box of shells I had 3 failures.
If you pull back on the bolt handle about 1/2 inch you will see that the parts of the bolt seperate a bit and expose a pin, about 1/8 inch in diameter. This pin works its way out so that on the return travel of the bolt, it blocks the pieces from closing. It will not fire the next round in this condition becasue the bolt is not completely closed.
I assumed that the disassembly and cleaning of the gun for bluing probably re-orientated the bolt parts and now they were loose. I took it to Midwest Gun Works, which is a Browning recommended service facility for obsolete Browning firearms. MGW advertises that they have "ex-Browning gunsmiths".
They had it 3 weeks. They said they fixed it. I shot 2 boxes of shells and had 10-12 failures. I took it back.
They worked on it while I waited. The smith brought it out and 'guarenteed' that it was fixed this time.
At the range I shot 5 shots and had 3 failures.
If anything it has become worse through all the work that has been done to it.
Any advise?
