I've often wondered if heavy lubrication on your AR's bcg, can cause a chambered round to FTF, due to the lubrication getting into the UN-SEALED primer??? Is this possible? If so, then how quickly can lube get into a primer? I mean, does it only occur to rounds that have been chambered for LONG periods of time?
OR, can a chambered round be penetrated by the heavy lube on the bcg much quicker than this????
Is this even possible, or likely to happen?

On a similar note, just why are primers and bullets sealed? Are primers/bullets usually sealed just to keep everyday moisture out, or are there other reasons (such as bullets being submerged at times during combat??)
Is the sealant ALWAYS visible, or can some sealant not be seen? I know a lot of the sealants are usually red, (or green in my SS109 ammo). Is it always visible, or are some sealants not visible???


I cannot stand worrying about the chambered round in my AR, which stays in the chamber for quite a while at times.

I don't think it's physically possible to have so much lube in your gun that it could contaminate the primer. At least not that I've ever heard of.

Yea, I have to agree. I can't see that happening.

I carried a 44 mag all summer fishing in AK, it had been submerged(when I damn near drowned in a lake), drug through the kenai more than once. It dint have sealed primers/bullets and at the end of the summer I shot all the ammo. Ran fine. I also had unselaed 223 ammo laying in the back of the truck in wet weather for a few weeks it ran fine

I doubt you could have a gun that will contaminate the powder with lube.

The fit between a primer and the primer pocket is REALLY TIGHT.  So tight that you can't draw any liquids up into it through capillary action, and you can't get any solvent to soak down into the space for the same reason.

I've tried several times to kill primers.  I've taken primers out of the package and soaked them in WD-40, bore cleaner, alcohol, water.  Soaked them for days and weeks.  They all went off when I loaded them.  The primer is BUILT to be robust, and it would certainly take a whole lot of effort to get past the primary defense against contamination: the foil disc.  That disc goes over the priming compound, is larger in diameter than the inside of the cup, and is sealed in place with lacquer.  It's under the anvil too.  Ever try to get an anvil out of a live primer?  I haven't managed it, and I gave up a long time ago.  If you can't get at the foil, you can't get at the lacquer.  And soaking primers in even lacquer thinner will only dissolve the lacquer—NOTHING is getting past that foil.
