I been using only the orginal G.I. Rifle bore cleaner in all my surplups with corrosive ammo and in 30 years+ haven't lost a barrel yet.

I also made a mistake by not cleaning my barrel for 6 months after shooting it with corrosive ammo. Nothing happened to it so that tells me its how much moisture is in the area where we store our guns matters too and how wet the weather is in your area matters too. Corrosive doen't just happen by itself it needs moisture too and lots of it.

When i learned about the corosive ammo/salts i thought i would see a dump truck load of salt come out of the bore when i first cleaned it. Then i realized as a kid the corrosives/salts is in the primer so there really isn't that much in the bore. I think its a combination of time and how many rounds of corrosive ammo we actually shoot plus how we clean it that matters.

Wanna know what I do? And this has worked for me so far with zero issues-

Take the rifle home.

Put a pot of water on the stove, and bring it to BOILING

Disassemble kalashnikov pattern rifle

Drop parts into pot

Pour water down barrel and gas block


Lay out parts on towel and hand dry while still hot (the rest will evaporate)

When cool, spray down with lubricant/CLP of your choice.

Punch barrel with a few patches of clp.

Reassemble.

No rust, no issues yet. This is my SOP for these weapons with all MILSERP M43/N76 ammunition.

Blast away :D

Thanks from Pacman

I have been using glass cleaner after shooting corrosive ammunition through various guns (including my AK's), and I do not have any issues with rust. Of course, it is a bit time consuming on an AK, as one has to field strip the weapon and get the glass cleaner into every nook and cranny, but again, it works for me. After using the glass cleaner, I use Birchwood and Casey Bore Scrubber to clean the bore and I use Break Free CLP to clean the internal parts of the gun. I also leave a thin coating of Break Free CLP on all of the internal parts and in the bore just to be safe.

Of all the 7.62X39mm ammunition I have fired, I think the Yugoslavian M67 surplus is the best, so I do a fair deal of cleaning AK's after using corrosive ammunition.

OK I know I have posted this before, but looks like a lot of people are not reading it, and this is a pet peve of mine as I think that Windex is using false advertizing on the general public. It will not cause damage to glass, but it can to a gun fired with corrosive ammunition.

Read the full MSD sheet on Windex with Ammonia D 5 post up . Ammonia D is nothing but a trade name for the alcohol in it. NO AMMONIA !

Actually, I am not using Windex - I am using a generic glass cleaner that does not contain "ammonia."

That was my SOP when SKS's were $99 and 1100rds BTSC corrosive ammo was about the same.Ive fired up to 550 rds in an afternoon with that wildly corrosive ammo. And the boiling water ( with a bit of diesel fuel and dish soap)
and a rinse with boiling water( left a thin film of diesel oil) on all surfaces. I also ran a brush with WW2 GI bore cleaner down the bore a few times along with cotton swabs just to set my mind at ease.
The only time I encountered any rusting issues was an afternoon in the rain firing a full 550rd tin of that C SCBT 7.62x39.The avbove cleaning regimen rid the SKS of the surface rust inside the cas cylinder and non chrome portion of the gas piston.No permanent damage! Hard core weapons!

The Windex method has yet to fail me with my Mosin. Been cleaning it that way for 5-6 years now. No rust anywhere on the gun. So although it may not be the ideal cleaner for corrosive ammo, it still works.

Best way of dealing with corrosive residue is USGI WWII bore cleaner. You can still find it at gunshows and on Ebay. I bought a case off some message board years ago and it came in a box dated 1943. It's milky white if it's still good.

I am a long time MG shooter so I have shot a LOT of corrosive ammo. I have never found a method that works as well as WWII bore cleaner. Note that the GI manuals of the day instructed to clean the weapon the day you fired it and for three days afterward.

And there IS a difference in corrosiveness. Some ammo is only mildly corrosive while some will start to rust your gun before you can get home with it. WWII German was bad about that. WWII Jap ammo, however, was the most God-awful stuff I've ever used. It would most definitely start eating your bore before you could get it home!

I have learned that all east block steel cased ammo is eather corrosive or contains mercury fulminate in the primer. On the later reason it is prohibited on all military rifle ranges over here. I don`t want to spray toxic mercury into my environment.

Me too! Here is my story; In the past I have shied away from corrosive ammo because of rusting and damage that is can do to a rifle (that is if you don't clean it after shooting). After I read a bunch of stuff about the brass cased Yugo 7.62x39mm ammo, I read that it was only mildly corrosive and good shooting ammo. I decided to give it a try so I bought a case of it since it was the only cheap AK stuff out there.

I have a well used Pre-ban Norinco AKM type 56 with a AK-74 break on it to keep the recoil down. It shoots well at 100 yards and okay at 200yards with Yugo ammo (Sellier & Bellot blue box ammo is the best!). Since the ammo was corrosive and the rifle is old I tried shooting one humid weekend this summer to see what would happen. The AK-74 break did start to form a rust ring on the muzzle after 2 days which would eventually start to get bigger and lightly pit. I cleaned the rifle and the break by shooting it again and blasting off all of the corrosion. No other rust developed anywhere else, not even the gas tube.

Next time I went out I poured some Windex in a small little stray bottle and packed it along. After shooting about 80 or so rounds that day I strayed down the AK-74 break until is was dripping wet then wiped off the liquid with a napkin and put the rifle away. No rust developed at all on the break or anywhere else! So I can say that the Windex stuff did work for me!

Please keep it mind:
1) The Yugo 7.62x39mm stuff has a reputation of being mildly corrosive and some what clean.
2) The Norinco AK barrel is chrome lined and other parts are well carbonized from years of seasoning.
3) All corrosive ammo is not equal: I have seen corrosive AK blanks do a real number on AK gas tubes when not cleaned.

In summary:

Since its a chrome lined AK, I think corrosive ammo is okay with the Windex treatment. The Yugo stuff is very good and a great buy! Save the spent brass and recycle it at the scrap yard to get money back!

I still would not shoot corrosive ammo in any non-chrome lined rifles (WWI & WWII rifles) unless I had a beater to test it on. I have seen many a M1917 US Enfields with nasty bores, I would not like to have that done to my rifle it I can help it.
