I use Anti-Seize on the threads of the breech plug and nipple in my 700ml and it works great. You can get it at Acklands. It is made by Loc-Tite. I have left my gun charged for a whole season without any problems. Do you have a scope on your gun? I put 2 on mine and could not get it to shoot a good group, I finally saw that the gun was tapped off center and the bases were canted over to one side. It shoots great groups with the open sights. I'm gonna try the Burris rings with the inserts to try to center the scope.
