    I'm just throwing this out there... I'm sure others will chime in soon and verify or rebut, but I'm thinking because of the possibility of oils and such seeping into the casing and fouling the powder charge or primer.

    Quality ammo is pretty much sealed tight, and I have heard in high humidity a light coating and then wiped off with a cloth can help fight case corrosion. And never use a "penetrating oil!"

    Bottom line is... when your life is on the line, you don't want to be hearing a click when you expect to hear a bang!

    Keep your ammo dry and out of humid environments when storing it and you should have no problems.

    The old adage from one of my mentors back in 81 which holds true for everyone carrying a gun was:

    Shoot straight, keep your powder dry, and watch your back.

    That bolded part would pertain specifically to your question here.

    Bark'n hit it right on the money IMO. I've never seen a need "to use petroleum based lubricants on ammo" or anything for that matter.

    Keep that ammo dry [ IOW, keep it away from any contaminates whatsoever ].

    Ammo doesn't need lubrication.

    This needs a question...
    Why would someone be using a petro-based product on their ammo?
    The last Blood Moon Tetrad for this millennium starts in April 2014 and ends in September 2015...according to NASA.

    I had read not to use petro-lubrication in another thread and was wondering why is all.

    So the ammo can attract dirt... If your worried about your ammo you can try nail polish around the primer and around the edge of the brass where the bullet sits. paint it on then wipe it off. It will fill in any imperfections that may let moisture in.

    Prerssure

    I have also heard that a coating of incompressable oil around the cartridge in the chamber can increase chamber pressure. Not sure of the physics behind it.

    As for contamination, I did an extended experiment a while ago and soaked ammo in everything from salt water to Hoppes #9 for hours to weeks and the majority of it fired fine. None of the premium JHP failed, and only one or two of the cheap range ball failed. Most, but not all of the rimfire failed to fire. I still wouldn't risk it.

    They will also desensitize the powder if it gets inside the case or primer.

    Sometime after a field stripping some grease gets on the follower. If a mag is then inserted and a round is not chambered the grease will be on the first round in the mag. I try to not be so liberal with the Lubriplate but I like a buttery action so sometimes it happens. Will Lubriplate seep into a cartridge casing?

    anything gets into the primers on any ammo it will kill the primers and cause misfires, so keep all liquids out of the primer areas period
