don't know if you've sorted the the extractor issue, but i had the same happen with some reloads that i forgot to re-size and they were a little sticking in the chamber. I tried stretching the left extractor spring, that worked for a bit, so I put a small packer behind the spring and that's working well, if i start having trouble I'll find a heavier replacement spring. i also bent the left shell carrier inward a little as it wasn't ejecting loaded/weighted shells, if i do my bit the gun runs well.
