RE: My Accura is here
Except for the breech plug - a LOT less. Typically you wouldn't even need to swab the bore during a shooting session. Don't go crazy buying it though, you might not like it. My first impressions of the powder werenot all that great but I think I was LOOKING for something to complain about.
Be prepared to clean the heck out of your breech plug though. The carbon buildup can be pretty stubborn. People use everything from Coke to Hoppe's. A little drill bit will make cleaning the flame channel much easier.
