Accidentally tumbled primed .40 brass

[dogslayer1313]

I took advantage of the rainy day to sort some brass. I have had several hundred .40 brass sitting in the tumbler for at least a month. I found that I had already primed about half of them. My question is will these fire? The flash holes appear to be free of any walnut pieces. I didn't want to hit them with the air compressor in fear of moisture in my tank. Should I just reprime them or just load them and note that some may FTF? What really bothers me is how I made the mistake but its been so long ago I don't even remember tumbling them.

you should be GTG...If it was me... I would blast them with the air compressor.. Your not gonna get that much moisture to effect the primers.. I never drain my compressor and i have never felt any moisture or seen any come out of the end..

One way to find out if the primer will fire, load an empty primed case and pull the trigger. They are loud...........

Lol. Could do this I guess. My first thought was a YouTube video. But that's just me.

They will be fine, I wouldn't bother with the compressed air, just rap on the bench, and look inside. Primers are amazingly durable. I had 2000 that sat in my filing cabinet for over 20 years, and I tested one of each size, then loaded them. Not a single failure. Federals.

Yes they are!
Don't forget the earmuffs.

Like someone said earlier, primers are tough. I had one lodge in a crack in my garage floor after months of exposure, soaked in water as well...surprised it went bang when I hammered it.

Ok, stupid question here. Maybe. Is it safe to run a primed case through a decapping die?

I've read don't.

I just did this today. Needed to properly trim some already reprimed cases. Went slow and put a towel over the press.

I save all my slightly dubious primers that I've dropped or something and set them aside for plinking ammo. I just shot them up the other day. Only probs I had were with the thick cup SRP, my striker fired pistols didn't like them, but my Hi Point 995 did.

If your media wasn't overloaded with case cleaner, I wouldn't worry about the primers.

I've done it many many times without ever having one fire. That doesn't mean it can't happen, so take precautions.

Thanks, I've got that "bad" labeled can with various rounds that I can pull apart for safety and might as well save the brass. So far I'm not motivated. I don't mind really loud powerful explosions I'd just prefer to know they are coming.

This works just fine. Close the doors, muzzle into an old rag and noone will ever hear it.

Do. I don't advocate running the ram into the die at high speeds (who does this anyways??) but you're not gonna set off a primer by pressing primers out of brass.
