[QUOTE="4ked Horn, post: 57534, member: 11"] Jerry. I will try to describe what I meant earlier about it not cycling by hand. When I pull the bolt handle to the rear and let go the bolt will begin to move forward untill such time as it also begins to lift the shell lifter. This portion of the mechanisim is a rearward and upward force against the bolt carrier. It is this point that is the most slugish or the point where the bolt stops. A quick forward assist usually gets it over the hump and it then moves forward to lock up. When the gun is freshly clean this problem is non existant. Previously when the gun was run without lube the problem crept back. Faster in the cold humid environment than in a warm dry climate. That is when I decided to try extra lube to see if it infact was powder residue build up. My though is along the lines of sanding metal or honing a knife with oil on the paper ot stone. It is there to keep the particulates "floating" to prevent the abrasive from clogging. That test is pending. The gun is in very good condition otherwise. The recoil spring tube and piston are spotless and polished and lightly lubed. The internal mechanisim of the bolt assembly is loose untill lock up and the bolt head and lock up bar are hard chromed (which is what made me think of this option for the inside surface od the receiver body. [ QUOTE ] Most modern powders burn cleanly that I doubt that is the issue, especially in factory shells.
