I fired 330 rounds yesterday with no failures and minimal leading using cast bullets. I used the 45-45-10 method of lubing the bullets and sized them to .357. I used the Lee sizing kit because of the speed to size. Accuracy was excellent

I used two different bullets that I cast with a hardness of 14.

The Saeco 377 122grain bevel base and the Lee 356 120 flat base.

When I cleaned the barrel after the days shooting with Turpentine and Chore boy pads it cleaned up with only a few strokes.

I have been shooting cast bullets for over 40 years and the CM9 barrel does just as good as any pistol that I have used as far as leading goes.
