Hey guys more questions from the "rifle noob" category. So i just recently bought some 7.62x39 (500rdns) when i got my CZ and i am a bit concerned cause i have herd talk of people selling corrosive and calling it non-corrsive. Is there any way to tell which is which? My understanding is that the primer is what makes the ammunition corrosive? The stuff i bought was MFS 7.62x39 123gr zinc plated steel case and i paid 179.99 for the lot (500), he informed me (the gun shop employee) that it was non-corrisive but then about 3 weeks later they received more ammunition (not sure of the origin) and he informed me it was non-corrosive for 169.99 per 800rdns and then a couple days later it turns out it was actually corrosive so im wondering did this same thing happen to me? The reason im worried is because id like to take my rifle camping and not have to stress about the barrel rusting out in a couple days. Any help?

Also my second question, is there a premium brand of 7.62x39 that i can buy in small quantities?

Thanks, M-
 
Take a .22, if you are going camping and can carry ammo but not a cleaning kit then don't stress yourself out. I've been in a pinch and sprayed my SKS with REM OIL and it was fine a week later. On a $200 dollar rifle thats not that big a risk, yours is a bit more spendy.
 
There is a premium brand called Prvi Partizan, you should be able to find it in any store and they are slightly heavier bullet with soft points and very nice brass casing, perfect for deer hunting as well and of course non-corrosive :)
 
The MFS is non corrosive. If it makes you feel better post a pic of one of the rounds and we will tell you what it is. also if it makes you feel better bring some vinigar to poor through the rifle after shooting it ( neutralizes the salts that is the corrosive part ) with some WD40 to spray on after, wipe it down and your good to go.

Ill have to remember the vinegar trick when i go camping. Thanks :). If i dont clean it for 2 days (with no vinegar or cleaning of any kind) and shooting non-corrosive do i still run the risk of it rusting up?

Thanks again, M-

Vinegar is an acid. It will probably corrode your blued metal parts.

Just spray on RemOil as SilentSmith said above, and you should be good for many days.

$20 for a box of 20, but then you have good brass for reloads.
That being said, you will want to find some way to control the ejection of the brass rounds, or they will be thrown all over and lost in the grass and mud...

Or you could remove your gas rod and use it as a bolt action when you are firing the Prvi Partisan rounds.

Vinegar is a bad idea...use boiling water. Seriously. Take along a tea kettle and boil it up over a fire. Boiling water washes the salts out. Just take your stock off first...

Yeah i just actually was reading up on cleaning methods and i never came across vinegar as one. Just finished cleaning and detailing it squeeky clean using the boiling water method i found on this site. The gun is cleaner then when i got it brand new now :). Loving CGN!!!!
 
Why vinegar??? An acid will do no good to dissolve acidic salts: it is the water in vinegar that does the trick.. Acetic acid, if anything, will help corrode the steel..And vinegar stinks! Use water... Windex does not work any better than water either... In fact, anything containing lots of water will dissolve the salts (tomato juice, urine, beer, etc...) but why use them if plain old free water will do the same AND is less messy?

Drench with water (hot works better and will heat up the metal so that the water will evaporate more quickly afterward), scrub, rinse with water, dry, use a water displacement agent if you want (WD40) and oil (a spray can of lubricant will do nicely!)

I have never thought of that.. wow that is a great idea! Have you ever tried it? I could then imagine it being more accurate because you then wouldn't have the heavy bolt sliding back. The gas tube would be much more dirtier though.. very interesting thought never the least :)

Vinegar? Sheesh, It WILL remove the bluing, slowly, but it will remove it. Just like you can wave your finger through a candle flame, but if you leave it there for a long time......


I have never used boiling water, and often never clean the gun between range outings, just hose it down with BreakFree or similar CLP.
 
You don't even need boiling hot water. How can soliders find boiling hot water on battlefeild?

Warm soap water is all you need.

Any how, now Non-corrosive M43 is available on market. There is even a price matching war there.
 
You don't need boiling hot water - that is for sure, but the hotter the water, the better it dissolves salt. Heck, I've cleaned mine with cold water in a pinch before. Worked fine.

Non corrosive M43? In Canada?
