[QUOTE="Carman, post: 620274, member: 40372"] Thanks for the reply...that is something I will get checked out next. I read on another site that the number one cause is a layer of varnish that forms in the chamber from the cosmoline. The more you shoot it, the more this film heats up and becomes sticky...almost like glue. I just sprayed some easy off into the chamber and then used a chamber brush vigorously and then ran some swabs with solvent through it. The swabs came out VERY sticky. I repeated until the swabs came out clean and no longer had a sticky feeling. The chamber now looks amazingly better. I will go shoot it tomorrow and see how it does. The particular site where I read about this says that the problem gets worse the more you shoot it (which it did) because this varnish heats up more and just gets more sticky with each shot. If it is better tomorrow, I will clean it again while the barrel is warm. If I continue to see improvement then I will continue down this path. If it doesn't improve, I will make a trip to the gunsmith to check the headspace. I think the varnish is the problem as I went out and got a couple of the spent casings and they definitely feel sticky. [/QUOTE]
