Thoughts on RCC brass

[Pheroze]

I bought some loaded ammunition for my 400 H&H. The case stuck and I had to knock it out. I pulled one bullet and measured everything. It all seemed to be in order. And, while I don't know the powder used, the weight of the charge was well within the range I would expect.

From my pictures the cartridge seemed to stick at the belt. The case walls don't seem damaged, save on scrape on one side. So, I am questioning the quality of the brass.

The rifle shot great with my own hand loads FYI.

Has anyone any experience with RCC brass?

I am responding to your question in my 400 H&H thread to keep the reloading info together

This is a picture of my habdload after firing

Here is the RCC I had to tap out

I agree the latter looks like it was dragged across concrete. My handloads all look good save a few scratches.

I shot 7 of my handloads before chambering this loaded ammo that stuck.

Clearly the problem isn’t your rifle or your handloads. Something is sketchy about that ammo.

The extractor groove isn’t close to the same size on the left case. And There’s a bit of brass that is hanging down. A lathe couldn’t have done that- something pushed it, I’d guess during the loading process.

I’ll bring my comment over from the other thread- hopefully someone with more knowledge than me will be able to give you a more solid analysis:

RCC cases were lathe turned (company out of business). I’m not a machinist or metallurgist so take my comments for what they are worth: drawn cases are work hardened by the drawing process. Is it possible the bases on a turned case were not as hard as they should be and expanded more/rebounded less after firing and that’s why they got stuck?
