Corroded Ammo

[pyro3k2]

Just ordered a 1990's production Portugese 7.62x51 battle pack and there was some very mild corrosion on the brass of 60% of the pack. The very worst looking round had some discoloration on the brass that was removed with a Brillo pad and was freed and cleared of the discoloration with some brasso. No pitting in the brass of the worst looking round after cleaning, is this ammo good to go or should I cut the round down and messure the brass for deviations.

anyone?

Sounds to me like surface tarnish.
If there's no pitting, I'd say you're good to go. For plinking anyway.

I doubt you'll set any records for accuracy with it.

Some Portuguese and Belgian BP ammo has been reported with tarnish, but it's always been reported as good to go but shoot them soon because the brasso may cause a problem. It can eventually eat the brass away.

The discolored cases won't cause a problem just as they are, but if you insist on shiny brass, scotch-brite is your best bet,

Lots of work though.

...some very mild corrosion on the brass...is this ammo good to go...

I bought some surplus Swedish ammo. that had some significant "fuzz" on the cases. I cleaned off the fuzz, and it shoots just fine.

I did, of course, check for any corrosion which might have caused any thinning or weakening of the case walls. After cleaning, all of the cases were smooth, with no evidence of pitting. It seemed to be just superficial corrosion.

I've shot that tarnished ball in M1A's and FAL's with no problem but these
rifles have GI spec chambers which are not as tight as "308" type chambers.

Good to go I'd say after a slight cleaning.
