I had another question. When i was shooting the 460 reloads, I was noticing there was a a lot more soot like stuff on the outside of the empty cases, and there was also a ring of black on the breech.
All the .460 rounds were longer than stock shells, but I was only having the issues with the ones I reloaded.
Any ideas?
This sometimes happens when a load is not sufficient to seal the case to the chamber. I don't know how high you are loading, but you might try a little hotter load, or better yet, just neck size the brass if you are not using it in more than one gun.
