For your information or amusement, as you wish.
A week ago I was cleaning my handguns, and when I got to the lubrication stage, I was carefully dabbing oil here and there. I got to thinking about the where oil shouldn't be, which led me to recalling advice I have received from various quarters that I should avoid getting oil on the cartridges, particularly the primers, as it may penetrate and render the primer or powder useless.
But I wondered, "Izzatso?" and decided to run a little experiment.
I grabbed 10 rounds of CCI Blazer aluminum-cased FMJ target ammo, in 9mm, a bottle of Militec-1, and a can of Kroil penetrating oil.
I chose the target ammo for 2 reasons. One, it is (relatively) cheap and if I ruined it, I wasn't out $8 or $10 or $12 dollars. Two, I figured that if any ammo was susceptible to oil penetration, it would be the cheaper stuff rather than the premium ammo. I figured budget-priced ammo would not have sealers, metal and primer stuff would be lower quality, etc. (Not that I don't like CCI Blazer - I have loads of the stuff -- but it is practice and plinking ammo, not first rate carry ammo).
I used Militec oil because it is what I use regularly on my guns. I used Kroil because it is supposed to be highly penetrative, and I figured it would be most likely to slither into any gaps or poruous metals.
I marked five rounds of Blazer with an "M", five rounds with a "K", and lined them up in an empty ammo tray. One drop of Militec on each primer of the "M" rounds. Then tried to put one drop of Kroil on each of the "K" rounds, but Kroil is so runny, it doesn't really form a drop, it just ran all over the base of the cartridge. Figured that was good enough. I carefully set the tray in my gun cabinet at 2200 (10 pm) last Monday night.
Today, Tuesday at 1700 (or five hours short of eight days later) I took the tray out (which still had visible oil on the cartridge bases/primers), grabbed my Kahr P-9 and some other guns, and headed out back to the range.
I wiped visible oil off with my Field Expedient Cleaning Material*, loaded one round in the magazine at a time (just in case I had engineered a squib round), took aim, and fired. Checked to make sure I had a hole in the target and that the barrel was clear, repeated nine more times.
All rounds fired. Some of the cases look a little smoky on the outside, but every bullet raced down range.
I don't intend to start oiling my cartridges, nor do I recommend you do so, but I found it interesting that I didn't encounter ANY failures. I may expand this test later to include more oil types and more brands of ammo, but for now I am not going to worry too much about contaminating the ammo with the minute amount of oil I put on my guns.
I do think keeping oil out of the magazines is a good idea in order to not attract dirt and to not tempt Fate generally.
