Lithium Grease in Barrel?
Hi all. I just paid for me what is good money for a CZ 527 American in .223. I know that there is no real consensus on barrel break in and everybody has different opinions, but I was doing some reading on cleaning and accuracy and came across this site. Part 4 talks about swabbing a clean barrel with lithium grease then swabbing out to leave a light film before firing. What do you guys think of this? I would ask at least read it before chiming in. This is my first what I would call truly nice rifle and I want to treat it right. Thank you.

sounds like a long term storage thing. otherwise you will more than likely have a borderline barrel obstruction problem.

Grease inside a barrel you're about to shoot sounds like a bad idea.

To treat your barrel right, just keep it rust free and don't fire rounds fast enough to cook an egg on the barrel. You'll be fine. To clean your barrel get a high quality one piece cleaning rod, bore guide, and plastic jags. Use bore cleaners your choice.
In short keep it rust free, keep it cool, and if your gonna clean the barrel clean it the right way. |

Light coat of oil I have heard of, light coat of grease never. Oil is much more volatile, a light coat of oil will burn away with the first shot. After that, the rifle will settle down and shoot consistently. Grease, being less volatile, will take longer to burn away. But, you know what they say: if it's on the internet, it's GOTTA be true!

I know. It is the first time I had heard of it and frankly his scientific arguments are beyond my understanding. I am wondering if there is any merit to them.

You want to clean a firearm after every use. And when you finish that cleaning, you want to leave a thin film of oil (or grease) in the bore to inhibit corrosion, but that film of oil (grease) is scraped off the walls of the barrel by the oversized bullet and any remnant that might happen to get left behind is combusted by the burning powder. |

And, yes, I know that in the last post I said:
Quote:
The fact of the matter is that the first round shot out of a gun strips the barrel of (essentially) all the oil/grease that was used to preserve it the last time it was cleaned. Leaving it uncleaned means that the hygroscopic (i.e. water-attracting) by-products of the powder's burning are left in the barrel. Shoot the gun regularly and those water-attracting by-products will get pushed out of the barrel (just to be replaced by new water-attracting by-products) but get sick for a few weeks and when you return to your gun, you may not be happy with the result. So, unless you have an accurate crystal ball, clean your gun every time. |

There are some old guys (like 60+ years ago) who would coat a barrel with lithium grease and then set it outside for a few days. The grease absorbed a little water and oxidized the edges of the lands and any burrs. Then they would clean it and shoot it. It was a shortcut to get a little better accuracy from barrels that were not of the highest quality to start with. I highly doubt it would yield any benefit with today's barrels.

When I’m done cleaning I run a patch of Kroil, and then a dry patch, but I wouldn’t put grease in my barrel. I only put grease (I use RIG) on sliding parts, and then I use a q-tip and only put a thin film.
As was mentioned, lithium grease might be good for storage, but that’s about the only reason that makes sense to me. Removing the edges of your lands doesn’t make any sense to me. I’d rather have tool chatter and sharp rifling than than rounded lands. I know at least ten barrel makers who agree. |

The only times I use grease in a barrel is when I am fire lapping. That grease has the grit in it.
Otherwise, it is only a protective coat of a light oil that gets removed before the next firing session. |

Grease absorbs water? Grease causes oxidation?

Gen Hatcher has written a lot about greasing bullets and grease in barrels and the excessive pressure that occurs.
If you was to do some checking. Target shooters, HP, Bench Rest, ISU small bore, etc. most always never shoot matches with clean barrels. They always take a few sighting shoots. Use to call them "fouling shots".

It has been shown that a single drop of water can throw a bullets point of impact off by a large margin.
I don't even want to think of what a greased bore would do to the point of impact. I was taught to clean the bore at the range after I finished shooting and then do a thorough cleaning when I got the rifle home running an oiled patch through the clean bore. Before putting the gun into service I run a tight patch through the bore to remove that lube and the dust(or bugs) before I fire the gun. The gilding jacket is self lubricating and doesn't require oil or grease to make it slide down the bore. |

Weren't there some old (turn of last century) military rifles that actually required greased bullets?

Lubricated cases, not the bullets, as I recall. They needed the cases lubed in order to function in the gun at the rate of fire.

"...Lubricated cases..." Yep. Very early M1 Rifles and other semi-auto experimentals used lubed cases. Caused more trouble than it solved. Proved to be a bad thing in the field too.
No grease or oil in the barrel except for long and short term storage respectively. Reading only part of Hermann's dissertation won't help. Mind you, the 'About the Author' link goes to a sales page.

Lithium Hydroxide, which is what is in Lithium grease, is hygroscopic. Yes, it absorbs water and really should not be used as a lubricant in firearms at all, especially AR15 barrel nuts.
Some other compounds used in industrial greases are also hygroscopic. |

My practice with any new or new to me gun is to run a boresnake thru it. No barrel obstruction therefore good to go. Shoot the gun.

Do note that the "old timey" instructions to leave a thin coat of oil (never grease) in your bore for STORAGE, also told you to run dry patches through the bore until they came out clean, BEFORE shooting.
Grease in the barrel, ok, put cosmoline on the rest of it, and store it for 30+ years. Otherwise, no...

The Swiss shooters have used grease in barrels for many years. Take the warm barrel run a greased patch down the barrel and let it sit until the next shooting session. Then before shooting run a dry patch down to remove the grease. Worked for them, many 1911 and K31 barrels look next to new.
Here's a link with some info on it http://theswissriflesdotcommessagebo...ml#reply-43958

But that has nothing at all to do with what the OP is talking about, if I understand his post correctly.

My experience is that shooters use too much lube , whether it be oil or grease !! I've used RIG for years but lightly .Storage ? Light coating of RIG , inside rust preventative paper .It's ready to fire !
