Tried the 610 today with cast 180 tc with BH-18 and 10mm brass rather than the 40S&W brass. There was less barrel leading with the use of the 10mm brass than when I used the 40S&W brass. Tried three different powders with bullet velocities about 975'/s. Best powder/bullet combo was Unique, with almost no leading after twelve rounds. Will lap the bore today after cleaning.
