Czech 7.62X51 ZV 69 (re-visited)

[Grinder]

While going through my stash looking for different 7.62X51 ammo to chrono, I found some Czech stuff. Marked :
ZV 7.62 69
Primer is black colored.
The 20 rd. (2X10) box is light blue with no markings.
Does anyone know if this is corrosive?
Years ago on another FAL board a guy was looking for this stuff because it shot so well in his rifle. I've had it a long time, but want to be careful what I use it in.
Thanks

I maybe wrong but I think it is.I remember seeing an ad in SGN for a case at a very good price,I looked further and saw BE/C.Berdan primed and corrosive.Like I said I might be wrong.Do you know what year it was manufactured?If it was made in the 70s I'd say it is corrosive.

I assume the 69 means 1969. Unless I hear otherwise, I will treat is as corrosive and save it for my camo beater in the works.

I have some of this stuff. It's supposed to be corrosive but from shooting it in my fal it must be mildly because i have seen no rust in the gas system. The way to test if it is i'm told is to pull a bullet and powder and then pop the primer on a plate of carbon steel and see if it rust. Never did it so not sure if it works. bye

I used to shoot it in my Steyr SSG. Really got good groups with it. Don't know if it's corrosive but I never let the sun set on that rifle without cleaning. Last I saw was about 10 years ago.

FWIW, the large majority of 'second world' European countries still use mercury salts in their primers. This is the 'corrosive' in corrosive ammunition. It is 69 year-of-manufacture: you can bet it's corrosive.

ZV69 is definitely Czech 'military', not civilian.

Some milder than others.

I implore you to clean properly soon after firing. You might not see it, but it will begin corroding, especially the hot gas tube and barrel, nearly immediately.
