I have had this Browning Gold 3.5" for 3 years. I usually hunt waterfowl with it using Faststeel loads in 3.5 BB's. The first year it didn't jam much and worked pretty great. The second year things started to suck. I would get off two rounds and by the third round it would jam.
I cleaned it thorough including the gas ports in the barrel. Ive heard on automatics you don't want alot of oil. So I tried that, keeping it real clean. It would shoot 6-8 rounds great. Then Jam. Then my experienced duck hunter friend said no, you need to use Rem Oil and lots of it, because thats what he does. Same results. Only when its real cold the bolt is slow to cycle.
So I have this 900 dollar gun stripped apart in my closet completly cleaned. I have heard these particular guns are notorious for jamming. I would like to know if there is something else I could try that I didn't think of. I bought a new Ruger O&U stainless duck model. I just wouldn't feel right selling this gun to someone, in this condition.
