I bought some of this "ZRA9SXTC" ammo from SGAmmo:
http://www.sgammo.com/product/winchester/500-round-case-9mm-winchester-ranger-sxt-147-grain-hollow-point-ammo-z-ra9sxt
I received it today; not exactly happy, though. Concerned, too, given that the merchant has no contact email or phone number...!
In one of the cases, about 50% of the ammo has something that looks like corrosion around the primers. I've never seen this before; some pics are below.
In addition, the part number on the web site (skew and part number on box) is ZRA9SXTC, but I received ZRA9SXT. I believe the C prefix refers to the primer type; I'm waiting for Winchester to confirm.
I filled out their "contact us" web app form; we'll see how they respond.
Has anyone seen this material around primers before?

Edit:
I scraped some of the stuff off of a box and took it to the range. It seem to shoot fine, anyway. Nice soft recoil, very clean shooting. If not for this stuff around the primers I'd be very happy.
I'm not certain it's corrosion, although it looks similar. It seems to be small granules that look like sand but are much softer.

PS: Anyone know what the "C" suffix means on Winchester ammmo? re: RA9SXTC vs RA9SXT
***** UPDATE ******
Well, customer service is excellent at SG Ammo. I've already received a response from the owner, Sam Gabbert. He assured me that it's just organic tumbling media from cleaning after assembly, but offered a full refund if I wasn't satisfied.
I scraped some of the material off of a few rounds, and it does seem to be a soft organic material. And, as I noted earlier, it shoots just fine (really nice, actually).
Kudos to Sam for his customer service. I would definitely shop at SG Ammo again.
