M1NM has it right. Pick up the bulk HXP and load your own en blocs via the CMP. No doubt Larry Potterfield has written a check to the CMP in the past, but might as well directly support the program that probably supplied your M1. Good folks in Anniston. :-)

My heart sank when I read this thread considering I just bought a bunch of "non corrosive" surplus on clips from the miwall booth a few weeks ago at the cow palace gun show. I ran about 30 rounds through my dupage garand and just ran a bore snake through it when I got home like I always do, at least until this thread prompted me to go look in the safe again.
Sure enough it had enough rust in the barrel to make my mosins snicker
Ran glass cleaner, water, clp, patches, and a brush down it for the past hour and its for definite pockmarks down the barrel.





I wasn't even aware there was corrosive m1 ammo out there,I thought that was one of the perks of shooting a garand. Live and learn,, hopefully others don't make the same mistake I did.
Iirc these garands from dupage had a fresh barrel and it was clean. I was really happy with the groupings I was getting from it too, I wouldn't trip much on it if it were one of my mosins but this is another story. How bad is this going to affect accuracy?Comment

Watch out if you ever find some of the Korean surplus M2 ball. Some of that was corrosive too and prone to head separations.My heart sank when I read this thread considering I just bought a bunch of "non corrosive" surplus on clips from the miwall booth a few weeks ago at the cow palace gun show.

Blackrat, you poor soul, my Garands and I feel for you. About the only plus here is you saw this now, not the next time you hit the range...
Also need to be watchful of the early US stuff, through ww2, it's also corrosive. and it is known to pop up in cans of hxp from the cmp, as well as the occasional tracer round...Last edited by jthesby; 01-29-2015, 2:18 AM.Comment

Don't forget to clean the gas system also. FYI, here is a link to an article which shows dates that non-corrosive production was started by the different manufacturers.
I do not have personal experience with the validity of what is shown, but use it as a guideline when buying.
Also, here is a link to a CMP thread that discusses the issue.

Gas tube and piston/rod are in good shape, very light surface rust on the tube that should come out. Bolt face and crown weren't too bad, light brushing with a brass brush cleaned up most of it. Barrel got the worst of it by far, hopefully she's still a good shooter.Comment

Everyone on Calguns keeps talking about TDS. I never knew we had so many fish keepers!
The TDS on my 10gallon tanks 110ppm
The TDS on my 29 gallon tank is 150ppm (due to substrate)Comment

It is are was made in a third world country, if that doesn't raise some red flags I don't know what will. There was recently a load of Iranian 8x57 and M2 ammo that hit the market, nothing but bad reports from that as well. If it was being sold at scrap prices that would be one thing, so about $.20 a round is what I would be looking to spend, and then I would be pulling it down, re-using the projectiles and maybe the powder and that's too much work.
Not all corrosive M2 ammo is bad, but anything not made in the US should be considered corrosive until proven otherwise. When I fist got into Garands, I bought a bunch of KA headstamped ammo from MiWall and other sources that was sold as mildly corrosive. I cleaned my rifles well but forgot about my dies, the resizing die got a case of the rust that I had to deal with. The KA brass was good, I am still shooting some of it.www.culinagrips.com

You're partially right, but you have to add "Carbine" after "M1" in order to be totally right :-) Or so I've always read.YOU NEED A GUN TRUST.
