Could cleaner chemicals cause FTF in a revolver?

By spraying cleaner in the chambers and wiping it out, and then putting the rounds right back in?

Could gun oil/chemicals cause them to seap into the rounds and damage the rounds themselfs??

Should you wait like a day or so?

I know its different than a auto because a revolver has ALL 5/6/7/8/9/10 shots chambers loaded, while a auto has just one.

I never seen any warning on the labels about this, that cleaner could cause harm to ammo...:confused:
 
If you're wiping it off (and running a dry patch through the chambers) there shouldn't be a problem. You do need to make sure the area of the firing pin is dried. The only problem I have ever heard about is if there are copious amounts of solvent that soak into the area of the primer. I've personally never had that problem and I have always used solvent to clean my revolvers. In short, nothing to worry about.
 
I've heard of something similar, but it happened with some local cops who were too lazy to properly clean their guns after a range session. They would fire off a bunch of rounds, reload the gun, then spray the entire thing down with a cleaner like CLP and just wipe off the excess. The oil would penetrate the primers and one Cop found out the hard way that his cleaning method wasn't the best. Luckily his backup took the time to properly clean their guns.

However, the root cause there was spraying oil on the primers of live rounds. Having a little excess oil in the cylinder bores isn't going to do anything.
 
The biggest culprit for killing primers is any oil that is silicon based. Silicon has the ability to travel great distances and spread out to one molecule of thickness. And silicon WILL kill primers by capillary action; It's not an old wives tale.
 
I have actually done this on purpose with copious amounts of wd40, Kroil, and silicon based lubes with perfect success after literally days and days of loaded rounds with puddles of oil on the primers. The rounds were nose down in a block. That is a real story, not someone heard, or some cop somewhere one time etc. Every round fired.

Someone else did a similar test, it may have been The Box O' Truth, I will check later and report back.

If it kills primers, then this is a repeatable thing. Not some fluke. I my self have attempted to repeat the often told tale of minute amounts of oil killing the primer from the outside of the case, and totally failed to kill any primers.
 
About 2 yrs ago .... I tested 6 completed rounds ....and 5 live primers....

I put all 6 rounds and all 5 live CCI primers into a little pint cup ...and soaked them with wd-40 ...for 2 weeks / dumped out the WD-40 ....and soaked them for another 10 days ...in Break Free....

then I loaded the 5 live primers that had soaked for 20 days ... into 5 new rounds...using my press..

and after I wiped the live rounds down ( I pulled 1 bullet of the 6 rounds ....and dumped the powder out ...and it looked fine - no migration of liguid into the case / so I put the powder back into the case ...and reaseated the bullet in that case.

I took all 11rds to the range.....and all 11 fired normally !! ( slow fire ..) but no issues / they all felt the same ...no extra smoke ...no nothing .../ I think its an old wives tail....
 
9mm:

If you load ammo with case lub on your fingers and you touch your primers when you inseart them into the primer punch you might kill a primer. I have never had a pimer fail because of excess lub on a gun and I'm a man who believes that if a small amount of lub is good a lot of lub is better.

Semper Fi.

I used to clean my gun with WD 40 by spraying profusely after a range session and thoroughly wiping down and patching the cylinders and bore, started getting FTF's regularly. I stopped using WD 40 and used good gun oil, only lightly and running a patch through cylinders and bore after storage, FTF's stopped so I'm convinced that it can and does happen.:eek::eek:
 
If it happens then it is repeatable. That is how we determine cause and effect. I can certainly see how you would consider what happened to actually be a cause and effect relationship, but testing would confirm it. I have tested it to the extreme, as had another poster even going so far as to soak live primers prior to the loading process. All fired for me and the poster. Try it yourself and see. I would be interested in another person's experience in attempting to bust the myth so to speak.

I will relate another story, although I hesitated at first. The individual, who is very well known in the firearms community and who will not be named, was asked to provide 1000 inert primers for an educational program. Unfired, but completely inert. This gentleman soaked the things in WD40 for over a week and they were still hot. Loose primers in a pail of WD40. This story is utterly true.
 
wd40 is the gunsmith's friend.
And the clockmakers.
Why?
Job Security.

I have heard you shouldn't get too much oil in your chambers, for ammo/pressure reasons, not reliability issues. I have had wd40 completely gum up in cold weather.

I've fixed door hinges, tight bolts, and frozen joints with WD40.

So my answer is yes, if WD40 is involved, I COULD imagine FTF in some guns. If you are talking Triflow, or Remoil, or what have you, something made for guns, I've never heard of them causing a FTF (penetrating the ammo or otherwise)
