dents in brass

[Mark A]

I've read plenty of threads where posters say not to worry about dents in brass as it will get fixed as soon as the cartridge is fired. Does this include dents that cross the shoulder area of a bottle necked round? I'm curious if any gas will escape the seal before the brass is reformed.

thanks for any thoughts or advice, Mark

Yes. That's a common place for dents.

That said, be sure you aren't overlubing your cases. That can cause denting in the shoulder. Are the dents there after firing but before resizing?

Small dents aren't a problem just be sure they aren't large dents. Depending on the caliber and powder, it could up pressures. I've been making 300BLK brass and had to really keep a closer eye on them. It's a small capacity case and I'll be running Lil'gun and H110 so pressure can climb fast.

Yes, the dents were there before sizing. The range where they were picked up was gravel and it was at the end of a 3 day class. They got stepped on a lot.

I've over lubed a few cases before but they just squished down. I've not seen a case get a vertical crease yet. But, like everything else it is something to watch for.

I'm glad you mentioned pressure as I hadn't thought of that. My practice loads are pretty middle of the road so I should be safe but still it bears keeping it in mind.

Thanks for the info, Mark

The brass from hell . I rejected some because of really deep dents.

I put mine in a coffee can. They're primed already so I figure if I ever get bored I can put 2g of bullseye in there and fill it with creme of wheat and fireform them. I'm gonna have to be REALLY bored.
