Thank you "American Rifleman"

I had no idea of my recurring unsafe firearm procedure. April 2015 issue has a tear out pamphlet called " Guide for New Shooters" and on page 11 it says after cleaning a barrel to-"run a patch lightly soaked in oil down the bore. BEWARE: oil in the bore can create excessive pressure a dangerous condition. Run a dry patch down the bore before you shoot your gun again." Silly me, and I apologize to all the folk next to me at the range these last 55 years.

I have always dried my bore before shooting.

There has been some evidence that oil in the bore can also damage the barrel. As the bullet passes over the oil it can cause a dimple in the steel of the barrel.

Not real hard to wipe the bore before shooting.

Darn. Next you'll tell us you road your bicycle without out a helmet on when you were a kid.

Now, with something like Eezox, after the carrier oil flashes off, the dry film should well under a thou thick, so how would that be an issue?

Not trying to start an argument, just trying to understand. I can surely see a thick oil film, or machining debris in a new barrel being an issue though.

I usually use a bore snake to get the oil out before shooting. So easy...

I personally don't think it is an issue, and I've found that bore treatment. in a .22 rimfire with EEZOX, is a benefit in helping to reduce bore fouling and make cleaning that much easier. I wouldn't use a bore snake in any of my .22 rimfire bores, even if they gave those away.

I've heard this too...the part about oil in the bore causing excessive pressure. I wonder if their is a documented occurence of a barrel rupture resulting from oil in the bore.

I also wonder if its a volume issue - i.e. the .001" layer of oil on either side of the bore reduces the bore volume to unsafe levels, or an ignition issue like the "dieseling" you get in some high powered air rifles.

Either way, its good practice to dry the bore thoroughly after cleaning to prevent excess oil from running into the action and seeping into the stock. The bore doesnt need to be soaked in oil to prevent rust.

Seems like this would be a real concern to center fire rifles with smokeless powder & jacketed bullets. Non issue for a shotgun and since you all got away with it for 55 years then I guess a .22LR with soft lead and black powder pressures is ok too.

There is already lube on the outside of 22 bullets. An oil film maybe more lube than desired but not a serious problem?

The gun cleaning kit I got around the time of my first gun had a guide that stated you should leave the barrel oiled when put away for long storage, but dry if in frequent use. Don't remember if it specified that you should dry the barrel of a stored gun before use and/or always forgot to anyway. I do, however, recall one of those times noticing a difference in the report of my first shot vs all that followed. Never looked into the science behind it, but randomly assumed the charge ignited the oil and made the shot a bit louder. It's a Ruger Single Six Hunter, which is built like a tank, so it never concerned me enough to look into it and I generally consider my centerfire revolvers in use, so I haven't left them oiled for this to potentially be an issue.

I do generally oil the chambers of my revolvers for feeding/ejection reasons, however, but it would be a short jump before the cylinder gap.

I just clean my guns the way the US Army taught me.

1. Brush with some Hoppes #9 bore cleaner on it 5 or 6 run-throughs.

2. Repeatedly run a Hoppes #9 soaked patch down the bore until is is pretty clean.

3. Run a dry patch down the barrel. It should come out clean.

You are done.

This has worked for me on pistols and rifles alike. 20 million+ US servicemen can't all be wrong.

I use all Hoppe's stuff. 112 years worth of people using it to clean guns. Works good, and smells good..........

Pretty much as the OP described in the AR article.

Like any piece of precision machinery, a firearm comes with a manual detailing cleaning, maintenance and use. Put together by the folks who designed it and specified the metals used, tolerances, testing, etc.
I follow their informed advice.
