Accura V2 . Pretty much do the same, and use a acetylene torch tip cleaner on small flash hole. I was typing this when cnelk put pic up. That's the tip cleaner.CVA Optima V2. I use Blackhorn 209 powder. Patches until clean using Hoppies #9. Then dry patches. I will run a nylon brush through it to remove any potential sabot fouling. I soak the breech plug in Hoppies as well. Use a drill bit to clean the flash hole.
