I can make a lovely necklace. LOL

Good informative thread!

Yeah to add on.. Most American (pre 2010) barrels for arx39 were 308. Not sure bout American ak47s. Now most manufacturers make all 310 bores at the very least. Faxon, green mountain (both ak's and arx39) and ballistic advantage makes .310 barrels. And green mountain is us made barrels. I can confirm these manufacturers make 310 bores. Ballistic  Advan discontinued their arx39 barrels. Dunno why tho. Lol

Surface rust isn't really much a problem if it's taken care of quickly ish. My ak from ddi was shipped with the firing pin stuck in the prostrusion state. Had to use a wooden dowel and my small ball peen hammer to get it loose.  I sent jus the bolt  back and they refinished it in whatever coating. Forgot the name. It was rusted. I bought a couple new firing pins too. I was hoping they would have changed it but they didn't. The firing pin was pitted in various spots. The bolt itself where the firing pin rides look clean and shiny so I not worried but I do keep it greased up when stored. I'll clean it off when I go range. Just as easy as disassembling an ar15 bolt to me. The chamber to me looks like surface rust but I cleaned it as much as I could without using a steel wool thingy I bought from sechawaii. And use clp grease on it every month via patch on a bore brush. Just to be sure. Anyways, pitting would be the dangerous part. And pitting is derived from rust.

I also believe the Russian military or whoever in those countries don't clean as much is because they shoot a lot. I forgot where I read it but shooting it as if you were always training or in war... Minimizes the the corrosion from spreading faster. Only thing I can think of is because it's blowing the salts out ? Of course shooting more ammo adds more salt but maybe heat has something to do as well? Maybe with heat and bullets keep the salts from "settling in". Never tested it myself and mot sure how accurate that is.

Good but bad example: everyone knows driving you car .. Your engine heats up. Correct? Lol well your car will last longer if driven regularly instead of letting it sit around. Oil seals will harden if not used. But the more your car is driven the faster the seals will go as well because it gets hot then cold more often. Double edge sword scenario. Always good but always bad at same time.

Sorry for going off topic.

But thanks for the thread! I enjoyed reading it and experiences.

Oh and btw I use my range bag as a brass stopper lol. I make it so that its standing tall side up and my ak and ar brass hit the bag. Soft codura type material so it doesn't bounce as if it were hitting plastic. Been doing it since I started shooting back in 2007. Seems to work for me.

Oh forgot to mention.. People I've read who posted rusting from corrosive ammo.. Within the past 5 years of using those ammo.. Lives in real humid places like Florida, the carolinas, Louisiana. MAC (military arms channel) on YouTube explains and demonstrates a good way to clean ak47.

Just found this and news to me. 7.7 mm jap ammo and .303 British share same bullet diameter as ak47.


Although I may not use .312 ammo on my arx39, wouldn't mind the ak though as I've talked to Steve from ddi and he gave the go ahead with .312 ammo on his guns as they've tested it. I think arsenal is gtg with .312 bullet diameter ammo. Kind of stupid eh? Steve said GM barrels use .310 bore barrels. Faxon use 308/310 hybrid barrels but said I should use caution. BA techs are dumb . Not to be mean but they were useless to talk to. Their sales rep knew more bout the barrel I bought than the tech. Talked to 2 different techs btw. They basically said no though.

Haven't had rust problems yet with my rifles except for the 91/30. I shot three spam cans of surplus ammo through it years ago and cleaned it every time but now wonder if it has lasting effects. Ballistol usually does the trick but haven't been happy with it lately. I bought a bore squeegee so we'll see if that improves the shininess with the Ballistol. Maybe it's a seasonal thing. SEC seems to have a good supply of grease if I ever want to store the rifle for a long period of time.

That's actually a really good price for .312 bullets. I think I'll try the Speer .311 bullets I already have first.

I've shot an HK G91 a bunch before.  That and the FAL are super fun guns to shoot, but .308 (that's the versions that I shot) is damn pricey for shooting in a semi-auto since I would tend to go through ammo quickly.  Same thing with an M14/M1.  I'd love one, but I think I would go through ammo super quickly.  However, now that all the steel has been taken down at Koko Head, that takes away much of the fun I had with guns like that. 

Now the PTR 32 in 7.62x39 is a gun that I was also interested.  The cheaper 7.62x39 ammo along with some excellent online reviews (like Mrgunsngear) had me wanting that gun for a while.  I'll likely stick with AKs and mod one of the ones that I already have, but I think the PTR will continue to be on my wishlist. 

Never really considered reloading for 7.62x39, let alone brass ammo for AK due to one of my main reasons for owning an AK is cheap ammo.  I am really surprised at some of the prices on brass AK ammo though, as in about the same or even more than the FGMM that I have for my 700. 

Was talking about that berdan primers and corrosive concerns with one of my shooting friends who is a long time AK guy and he said that he believes most of the ammo that he's shot has been berdan primer ammo.  He's shot thousands upon thousands of rounds of 7.62x39 and his guns hasn't shown signs of corrosion, but he also cleans his guns regularly.  He also mentioned that most of his guns are chrome lined barrels.  My Arsenal SLR-101 has a chrome lined barrel and I believe my Kassnar FEG has a chrome lined barrel as well.

I bought 1,000 rounds of Tulammo non-corrosive for $310 at OGC. It's about $240 on the mainland. I then bought 40 rounds of American Eagle and 50 brass cases for reloading. I have to reload to feed my addiction. I have 800 of the Hornady .310 bullets and I'm looking forward to trying the CFEBLK powder.
