White Hots cleaned up easy but not as easy as the BH209, and I found that after 3 or 4 shots with the WH I needed to swab the barrel but with the BH209 I could shoot shot after shot without having to swab the barrel.
Wired, I had the same problem with BH209 before I started shooting 110grs and using only Federal or CCI primer's. My breech plug still gets a wet black greasy soot.
