Thread: Soot On Case Bodies

It did do it while I was doing some incremental testing with 2209. But it didn't seem consistent. There is a small amount of soot on the neck of the factory rounds (Hornady Superformance).

The primers are Federal 210. My '96 ADI manual mentions magnum primers with 2213 but the modern ones don't. I do know it's an incomplete burn ~86%.

The cases have never been annealed and are full length sized each time.
