I bought a case of the new Wolf Poly 7.62x39 recently and went shooting soon after. The few loose rounds left over afterwards were left in my range bag which is kept in a dry storage area between shoots. Yesterday I noticed the loose Wolf poly coated rounds had rust spots all over the steel cases. The ammo was never wet and was handled normaly. I checked the GI storage can that held the rest of the ammo and found no rust. The older style of varnished ammo had it's problems but at least it didn't seem to rust. Anybody else notice this problem?

I took some poly coated 5.56 to a shoot in February in the rain.  No signs of rust.

I have noticed that all steel cases will rust after shooting and left outside.

I put a few loose rounds of the Wolf poly in the refrigerator where it is moist. Will check it in a few days for case rust. Hulls will rust I suppose from the case stretching and breaking the protective coating when firing. Also the abrasion encountered in the chambering and extraction would have an effect.

There's no protective coating on the inside of the brass...that's where most start rusting I would suspect.

I've also noted that the poly coated Wolf *will* rust much faster than the old laquer coated stuff. (unfired)

I mentioned this on the phone to Wolf last week. (they called to talk to me about the squib loads I had in the 45 ammo)

The Wolf poly coat 7.62X39 ammo I put in the refrigerator doesn't show signs of rust yet after a week. I wonder if the rusty stuff I found was due to a lack of quality control.
Maybe a few rounds get through without the coating. How could you tell? I just use the stuff for making cheap holes in paper. For anything serious I use IMI.
