I've read two posts recently where individuals talked about lubing the inside of their case necks to help minimize this possibility of the bullets bonding to their case necks. This done in the effort to improve the consistency of their case neck tension. The more interesting procedure I read about was the use of an HB grade pencil from an art supply store. The individual coated the inside of his case necks with the pencil, and claimed the graphite in the pencil helped to ease the force required to seat the bullets but more importantly, provided more consistent neck tension. I've been considering using this method since it seems pain free, non messy, fast, and cheap. But I don't know if it would make a knat's *** difference or not.
I will tell you this the pencil idea is a bad one. "why", sounds logical? The problem is what will the pencil marking do, It will hot spot which will harden the case faster thus shortening the useful life you can get out of your case. Ok, now before you all freak out on me the pencil lead is not designed to handle the extreme heat from the powder "burning at it greatest temperature, right there at the neck" If you don't believe me ask any aircraft mechanic why you don't mark on exhaust or on turbine engines with a pencil this can cause engine failure believe it or not.
About the metals corrosion, you need the two dissimuliar metals and an electrolyte for metal to corrode. Electrolyte such as water. If you don't have wet ammunition it isn't likely to corrode.
The original question was about welding, no! the bullet does not weld its self into the case. If there is water around, then it can corrode to a point that the corrosion will lock together like vel-cro.
Does the bullet kind of stick? Sure it can when a bullet sets in a case you have two different metals against each other with an interference fit they expand and contract at different rates over time. As most people know some metals heat up and cool off faster than others which make them expand and contract at different rates. This is why there is a stick, so to speak.
Does it effect accuracy? Possibly if the tension is no longer uniform but if the tension is uniform why would it?
Well thats my two cents worth of'course I think I'm right. haha

QUOTE OF THE DAY
Before anything else, folks in Washington ought to be asking first and foremost, 'Should government be doing this? And if so, then at what level of government?' But they don't. The result has been decades of growth in the size, scope and function of national government. Today's governance of mandates, pre-emptions, regulations and federal programs bears little resemblance to the balanced system the Framers intended... A government powerful enough to give you everything can take away from you, anything. Our government must be limited by the powers delegated to it by the Constitution.
