I prefer a slotted brass patch attachment to a jag. I feel like I am just pushing crud into the breech when I use a jag. It also allows me to flip the patch around to get at the face of the breech plug.
Breech scraper.
Yeah, it's another thing to keep track of. Yeah, it's another step to take. But, it's a tool that produces positive results and no guessing if you're leaving crap building up on the breech plug.
