    Is this corrosion?

    I bought some winchester ranger off of gun broker. When I opened up the four boxes to inspect the ammo I saw a white substance around the primers of most rounds. Some worse than others. The nickel casings and bullets themselves look flawless. It's just the primer area that's affected. Is this corrosion? Are they unsafe to fire? Can I send these back? Can they be cleaned up or salvaged in any way? Little discouraged right now as I spent alot on these 200 rounds to be carry ammo as I've read such great things about the round itself and now might not be able to use it.

    You can call the company and give them the lot number and they will give you the date of manufacture. I am not wearing my glasses right now, but it does look like corrosion on the primers. I would contact Gun Broker and pose the issue to them. They should work with you on some sort of resolution to the problem, at least I would think they would want to. I have seen Winchester ammo that came new in the box that looked nasty, but nothing like what those primers look like. Again, I'm not wearing my glasses but that's what my old eyes think they see.

    If they don't resolve your problem for you I can see no danger in using them. I have shot worse looking ammo then that without any problems.

    I purchased 100 rounds of Winchester silver tips and noticed the same thing. Small bits of gunk around the primer made me very nervous. I randomly selected a magazine full (the worst looking rounds) and shot them at the range, everything was great. I carried and rotated the rest of the rounds for about a year before replacing my carry ammo with 147 grain rangers. At this point, I knew the police officer I had purchased the silver tips from had them for at least 5 years before selling them to me. The rest of the silver tips I had were at least 6 years old at this point and I decided to go waste them all at the range and see if I had any duds. Could have sworn the silver tips were +p when I shot the rest and they all went bang. point of my story, shoot a mag full of the worst ones through the gun you will be carrying them in. If they are all good, then you should be all good. Although, some of those primers look pretty awful. If you think Winchester will send you new ones, they I see no reason to keep them. Just my thoughts.

    As a mp we shot .45 rounds that were in a 55 gallon drum marked 1944 just had to wipe the green mold off of them but worked fine.

    So I shouldn't worry about it blowing my gun up I should worry about it just not going bang at all if anything

    No, that is not corrosion. That's the primer sealant Winchester uses. The granules you see might be from the media used in the final polishing process. My Ranger-Ts look the same. You're fine.

    This, is corrosion. be375c58.jpg

    At home, I had some old .308 and .30-06 hunting rounds that were stored in a damp-ish shed for 20+ years. Some of them were similar to the pictured rounds, covered with patches of light corrosion I was able to clean up with steel wool and they shot fine. Others were completely covered in green-blue thick corrosion, even the bullet. Those sit on a shelf now, because they're interesting.

    Glad there are eyes better than mine looking at this! Trust me, once you get a certain age bi-focals are your friend.
