sticky bolt syndrome
This topic has gone round and round, but bears a quickie just to pass along findings if for nothing else. \\
I stumbled on the sticky bolt when I purchased some steel cased ammo. Can't tell you what it was today, but remember the uneasy feeling when the bolt wouldn't cycle easily. I had been anal about cleaning and couldn't believe I was having trouble. In retrospect, I was using too much gun oil.
Ok so here's my take and its nothing more than opinion, like noses everyone has one. Here's what happened. My son and I were up at our favorite shooting site, and using the copper washed tin of ammo. He has a '43 Ishevsk M-44 and I was shooting my 9130. Both of us started experiencing the sticky bolt, and I was sure it was the ammo. The following week, when stiff operation continued, I reached into the back of the Jeep where our cleaning box was sitting and pulled out a tin that had a mixture that I used on my black powder 1868 Remington. Its Burts Bees wax, Olive oil and bore butter all melted down. I took a pinch between my thumb and forefinger and wiped it in my right hand. Now when I pulled out 4 or 5 rounds of 7.62 some of this slime got on the cartridge cases and low and behold the sticky bolt went away.
What I think happens with steel cases is that they are thousands thinner than brass. If you have any petro oil at all in the chamber the hot gases seep backwards and form a sticky glue that makes extraction stiff. If your bolt is sticky with any steel case or copper washed ammo, make sure you use an over sized swab to clean out any residual oil from chamber walls. Having an Italian salad before shooting and getting some olive oil on your hands might help too... heheheh
