Boeshield T-9 in rifle chamber and bore

I have T9 and like it. I'd use it very sparingly in the bore or chamber. I use it on rusty tools a lot and I've noticed one thing. T9 likes to build up a thick waxy coating where there is ANY excess. On a gun you're going to be shooting I'd use another product that can't build up like T9. I could imagine T9 running into the chamber after application and the gun is stood up. If it built up the waxy coating in there it could be unsafe to shoot. T9 would be perfect for guns in storage that don't get shot much. THis is the situation I use it for on guns. I read one account of someone in Oregon applying T9 to bare steel and leaving it outside for 5 years rust free. It's amazing stuff. Another great one that doesn't build up and works well if you're worried about rust in regularly used guns is Corrosion-X.
There are some uses where a waxy coating is desirable but the chamber of a rifle isn't one of them.

T-9 is fantastic stuff. I use it on the exterior of several of my guns, if I am either going to store them or take them outside into humid environments.
However, T-9 protects, in part, by leaving a wax film covering the metal. Probably not a big deal if a little is in the chamber/bore, and I would definitely use it for long term storage, but for corrosion protection of the bore/chamber of a gun that I wanted to be able to shoot without cleaning first, I would probably go with a thin coat of Rem Oil or something, followed by a dry patch.

I was thinking of spraying the Beoshield on a patch and wiping it on the internals and then running two patches of it through the chamber and barrel. That way there will be less build up than if I sprayed it into the chamber.
At least in theory.

I don't think that technique will give you problems, but remember the potential is there. The chamber needs to be the cleanest part of the gun. Lubrication there doesn't allow the expanding brass to grab the chamber walls. When this happens it greatly increases bolt thrust and much more stress is exerted on the bolt face.

Slight veer here - how well does T-9 work as a lubricant for action parts? I'm thinking particularly of the bolt and bolt carrier areas on AR and AK designs. I currently use FP-10 and it won't stay put on areas that are often uncovered, or that have loose tolerances.
Thank you for that question. It got me thinking 
Beoshield has wax in it and dries to the touch. Specially paraffin wax.
On a cast iron top used for woodworking (table saw, jointer, etc.), The wax in Beoshield helps wood to glide across the table. However, while it does reduce friction, I wouldn't call it a lubricant. It's purpose is mainly for corrosion prevention.
What got me thinking is that because Beoshield has wax in it, will it cook off inside a rifle? In other words, after firing many rounds will it no longer have the desired corrosion inhibiting quality?
Eezox, which is nearly identical in price, dries to the touch as well. Compared to Beoshield, how does Eezox stand up to the heat and pressure inside a chamber and rifle bore?

Eezox is a superior product IMO. T9 may have a longer lasting corrosion resistance I don't know yet. I run my own corrosion tests and the oldest ones I have are 3 years old. You can hardly make bare steel treated with either product rust. They're both great. From the testing I've done this far I've noticed thicker coatings definately last longer and are more effective(Eezox being an exception). Grease is a good example. Gun grease when applied very thin has almost identical anti corrosion properties as good gun oil. When grease is applied heavy it triples the performance of a good oil.
I'd use Eezox over T9 for everything but long term storage(especially in the chamber and bore). The only things not to like about Eezox are the smell and the trichloroethylene gives me a headache. From a corrosion protection standpoint it is the finest product I've ever tested along with T9. To date I have no samples showing rust after dozens of saltwater sprays and staying in my dusty garage in hot humid Nebraska summer temps.

Boeshield works because it leaves a waxy residue. If you apply it too thinly, it won't protect very well. Make sure you get it all out before you fire the gun.
I would guess that it makes a pretty poor lubricant. When the carrier has evaporated, the wax is quite...waxy. It's likely to be the worst of both worlds: gummy where you don't want it, but no real surface lubrication.

Boeshield applied heavily resembles candle wax if it had been rubbed on hot and dried. Onother good description would be congealed bacon grease. The stuff always stays a little tacky like wax. It's also one of the best things to use on a bike chain.
I was organizing my garage a couple of weeks ago and stumbled on my corrosion tests out there. This is an update for anyone interested. The Eezox sample is now rusted. The only samples I have without rust are Corossion X (26months old) and Boeshield (10 months old). Just 4 months ago the BF-CLP and Eezox samples were still rust free. They were both 22 months old at the time. These samples all got sprayed with saltwater for a week, then I put them up in storage after the majority of samples are severely rusted. Some tests are almost 4 years old.

You really do not want anything in the chamber since the case expands and grabs the chamber walls when firing. If it is lubed the case may not be able to expand and grab the chamber walls properly and this may cause excess pressure against the bolt face.

I think 40-60,000 psi is going to squeeze out any lube, at least any liquid lube, that might be in there.
However, you're right that you don't want lubrication in the chamber, and especially on the case itself, because friction between the case and chamber walls, under that 40-60,000 psi pressure, helps hold the case in place. A lubed case minimizes this and increases force on the bolt. Now that shouldn't cause immediate problems in most designs, but it isn't good for things.
Boeshield and gun in general
I used to be an avid trapshooter. I would shoot 300-1500 shells/day two days/wk.
I have been using Boeshield T-9 since the 1980's on both interior and exterior metal surfaces including the bore of shotguns and pistols. I have never had any trouble with excessive build-up (like you get with something like WD-40).
I have some guns that have been stored in a humid Iowa basement for over 10 years that were treated when put in storage and have not been treated since. None show any signs of rusting.
The "waxy" feel takes some getting used to on guns you use regularly but it sure beats oils that get on everything and wipe off without really protecting. The Boeshield has not damaged any of the wood finishes but does "bleed" into and darken areas with no finish (ie: where wood meets metal and is not finished.)
In summary, it is the best product I have found for preventing rust in storage other than cosmoline and also works well for guns that see a lot of regular use both as a lubricant and a rust preventative.

I was out looking for Boeshield just today. My local Sears does have it, but only sells it in a combo pack of a 12oz spray can and a 8oz bottle of "Rust Free", sealed together in one package for $24.99. Not worth it for me, especially since I want the liquid version and don't need Rust Free.
The boeshield.com website has the same price I saw at Sears, and Brownell's has the same prices I see at the boeshield.com website. But you get free shipping at Boeshield's website if you order $50 or more. If I do order any, I'll probably go through them.
Since earlier posting I've obtained some Eezox and tried it out. I really like how it dries to a completely dry, non-tacky, and fairly slick finish. It also wets the metal and that makes many metal finishes look nicer than they otherwise do. However, after reading up on the health risks of TCE, I'm probably not going to buy any more Eezox unless they come up with a new formula free of TCE. It's not good for you.
I should note that based on their MSDS, Boeshield and Corrosion-X aren't completely harmless or nontoxic either, but appear to be somewhat less harmful than the TCE in Eezox. I'd welcome comments from anyone in medicine or occupational safety, etc.
