Hi guys,

I am working on my first batch of reloads for my Sks and noticed that a couple cases have a small u shaped dent in the case mouth when looking from the top down. I resized them and it didn't fix it. lookiing from the top down into the case it looks kinda like ---u--- You can see where the brass is folded down.

The case is on good shape otherwise. Normally, I would toss it if it were any other cal but my 7.62 X 39 brass is in short supply. There is no crack just the u shaped dent in the top. Should this case be safe to relaoad with a mild load (14 grs of 2400)?

My hope is that the dent will get fixed when the rifle is fired and the mouth expands to release the bullet. As I said, I am trying to conserve brass but I want to be safe while doing it.

Thanks,
Cactus
 
My guess is it will be fine if you are able to seat a bullet properly, but hard to say without a better description or a picture. SKS will damaage a lot of brass, it wasn't designed as a precision instrument...
 
The bullet seated fine with a mild crimp. I loaded 5 rounds at 14grns and 15grns to test. and made sure that the bullet in the case mentioned above didn't move. I did the table test that I do for taper crimped pistol rounds. Put the round nose down on the desk and apply force to it and then measure the OAL again. All was fine.

Hopefully I can get a camera to take a picture of this to post. If not, I'll post the test resaults tomorrow.

The round fired fine but the dent is still there. I thought that it might be gone. Oh well, reload again and see how it goes.

Cactus, I suspect the dent is caused by how the rifle ejects the brass. If so, you'll keep seeing a new dent after every firing. I don't think it's anything to be worried about.
