What in the heck is this?

Ok I've been reloading about 32-35 years now and have never seen this. It's coming out of 22-250 brass that has been resized 5-6 times now. Only difference is a different die for the first time. I typically run H380 or IMR3031/4064 and CCI or Fed match primers. Looks like flake powder residue or carbon flake.

Just looks like carbon to me. I guess your new die sizes a lot more?

It has to be carbon as I have never seen that much powder residue from anything I have shot.
Maybe try a different powder for a change and see if you have less of what you have now.

Yea I tossed it on the wood stove coals and no ignition so carbon it is. The RCBS fl seems to resize the web area a bit more than my Lee's.

50 rounds I'll bet I got close to 1/2 a tablespoon out of them. Maybe time to invest in a tumbler.

That is crazy for sure.

Looks like the crap that came out of my suppressor. Flakes of carbon.

I have never owned or shot a 22-250 but I do shoot several 223's.
I use Tac powder for my 223 and a great load for my 308 with it too.
If you can find it anywhere it is a great powder with no residue left behind that I can find.
Yes I do use a vibrating tumbler and a tumbling tumbler.The tumbling tumbler with steel pins does the best.

I've literally gone thru a 5 gallon bucket of 22-250 brass over the years and never seen this before. Guess you never know what you'll learn!

The different sizing is leading to crud burst.
It should stop now

In the flightline, we call it, FOD ............................................................................................ Foreign Object Damage.

I hope you get it resolved.

H380

Would be the issue. Imo. The slower burn rate H450 (discontinued) powder in my 22-250 caused misfires & hang fires, using a magnum primer.

The misfires, when pulled apart, showed the primer fired, powder started burning, then stopped. No bullet movement .

Both H450 & H380 are using the same chemicals. I would guess more coating on the 450 to slow the burn rate.
