Have a bit of a problem. I let my brother use my M1 a week or so ago, made sure to tell him to use windex, because of the surplus ammo, along with a regular cleaning, after he got done shooting it. I picked up my rifle today, and the barrel is full of rust. Turns out that he used some off brand window cleaner his wife had, which contains no ammonia, and also didn't clean it after he dumped the cleaner down the barrel. I've been trying to get the rust out for the past two hours, the barrel looks like shit, and I'm highly pissed off. Any suggestions on how to get rust out? Would it be a good idea to use some of the Tubbs polishing bullets? He offered to pay for whatever it is I have to do to get it back to normal.

The damage is done, but for a short range gun it will probably still shoot fine.
where are you in OH?  I have several good shooter barrels I'll make a deal on as well as new Douglas Barrels.

I'm near Steubenville, OH. It is a short range gun, only because I don't have access to a range longer than 200 yards. I'll send you an email at adco's site early next week to see what kind of barrels you have.

Thanks for the help.

Before you change the barrel shoot it , sometimes a rusty or pitted barrel shoots good. I had a SMLE with a bore that looked like a sewer pipe and it would shoot an inch group at 100 yards

Was your brother shooting corrosive ammo?  If so, why would you want to have corrosive ammo shot through your M1, especially by someone else?  The guys
who use Windex after shooting corrosive ammo, do so as a first step to dissolve the corrosive residue immediateloy before cleaning the way they would with non-corrosive ammo.  I've shot corrosive ammo through some old Mausers and Mosins and used Hoppe's #9 to clean, with no problem.  As to your barrel, I'd say it's ruined but I really don't know who's at fault here.  I NEVER loan firearms.  I'd call ADCO if I were you.

Clean the hell out of it.  Maybe try some JB Paste.  See what it left.

Fer the love of Christ, already. Ammonia does nothing to the corrosive salts. It's the water that dissolves them and carries them off.

Since you have little to lose, put some rounds through the barrel and see if it still shoots all right.

8mm size stainless bore brush...

Thanks for all the replies. I cleaned it the best I could, took it shooting today, and it still shoots as good as it did before. Whatever rust was still in there is gone now. She's been scrubbed, cleaned, re-scrubbed, re-cleaned, greased and put away til the next range trip. May try some of the JP Bore Paste.  Lesson learned today... the next time my brother, or anyone, wants to use any of my guns, I'm going to refer him to the CMP North store.

You need to pull off the gas cylinder and clean under it and also clean the end of the Op Rod.
Its really not worth the wear and tear shooting corrosive ammo in a gas operated firearm. Save it for bolt guns

If you clean it promptly and properly, then shooting corrosive ammo is no different from non-corrosive. Definitely agreed on the gas cylinder and op-rod. Clean anywhere the propellant gasses may have come in contact, i.e. bolt, gas system, etc... Heck, just clean the entire gun while you're at it. I put 900 rounds of Yugoslavian 8mm through my FN49. No problems. Shot great.

Its no problem if properly cleaned but everytime you remove the gas cylinder you are putting wear on the barrel splines which will make a sloppy fit and result in poor accuracy.
Barrel splines can be peened to retightened but why use corrsoive ammo when good non corrosive is still available

The only reason I had the old, corrosive ammo was because that's all the gun shop had in stock. Didn't know any better when I bought it. Got my fed ex tracking # from CMP last week, my 4 cases of ammo from them are to be delivered tomorrow.

ok, im curious what M2 ball ammo is corrosive.

ive shot ALOT of Greek through my garand, no cleaning, no problems.....

Just looked up the headstamp, and according to the CMP forum this is Taiwanese made, corrosive ammo. Bought it in a spam can, on en bloc clips, head stamp reads "30 60A 58". The spam can itself has a lot of Chinese writing that I have no clue what it says, with the numbers "M2", ".30", "60A-9-127" on it.

That is good ammo. I got a good deal on a bunch of that ammo several years ago. I bought it cheap and so far I have shot several thousand rounds of it through two Garands.

Since I know how to clean my rifle I have never had any trace of rust. My bore is still bright.

One of my Garands shoots this as as well as my carefully crafted handloads using high dollar SMK bullets.

I don't get why so many people think it is so hard to clean a Garand. Every single round fired through the Garands in WW-II was corrosive.

I wish I had a million rounds of this "junk corrosive ammo".

Don't remove the gas cylinder. There is no need to remove it to clean up after corrosive ammo.

Thats your opinion, it needs to be removed and cleaned underneath

It absolutely needs to be removed. The gas cylinder may be OK, but the bottom of the barrel and the gas port need to be cleaned.

All this can be cleaned with the gas cylinder in place.

How you gonna clean the pad(s) and splineways with the GC in place?

The Taiwanese also sold their ammo to the Israelis.  I've seen belted 30-06 M2 ball for sale in spam cans with Israeli marking for sale before.

Yep, sure it was my brother. I'd take credit for a bonehead move like that. I may be an asshole, but I'll take credit for what I screw up. On a lighter note, my two cases of Greek M2 came by the big white truck today, so I should be good to go for a bit.

Korean M2 ammo with KA head stamp is corrosive. Korean M2 with PS head stamp is not corrosive. Both are boxer primed and the brass is very good.
