Well let me put it this way. It could be colder that a well diggers butt sitting in a goose field. The gun hasn't been cleaned for a year and it will shuck and cycle shells with no problems at all. I read a gun writters report about several different 12 gauge autos that he tested. The test consisted of pouring a mixture of muddy sandy water down the barrel and into the actionof the guns involved.They werethen taken on a actualmorning duck hunt in very cold weather. In the afternoon the test continuedwith shooting clay pigeons.The writter reported the Browning Gold not only passed the test with ease, but that it in fact beat out all the other autos including the Super Black Eagle. I was very skepticaland thought the writer was full of it. But I also wanted a 10 gauge auto,so Ihad to choose between the browning and remington.To help memake a decision I tracked down this writters work number and gave him a call. We ended up talking for over a hour, I learnedthat the 10 gauge gold was no different than the 12.Then he flat out promised me that if I didn't like the gold he knew several people that would be more than willing to buy the gun from me. Well to make a long storie short I still have the gun and I love it. It flat out doesn't jam and being honest the only jam I have had was when I mixed up a 12 gauge 3.5" with my 10 gauge shells. That did jam the gun, but not for long. My gun is the older style (6 years old) and build like a tank. It can take a pounding and keep going. I alsohave the Nova pump and several other 12 gauge pumps and autos but none are as good as my Gold 10. I have usedthat gunfor both ducks and geese over decoysand have no clue how many shells I have fired out of it. But one thing I do know and that its just being broke in.[8D]I expect that gun to last me the rest of my life andthen some.
