Have a nickel Scholfield 45 and been loading for years, but I loaded up 50 some 45 Schofield Starline brass with 4.6 grs Trail Boss with a 20/1 cast 230 gr. RN. .451 dia. all shot fine, and close to P.O.A. When done firing the Schofield was really dirty, and found one split case. Wondering why so dirty, as I have used 5.0grs. Unique and was a litlle dirty but not like this. I'am thinking light load cases not expanding enough to seal to the cylinder, or oversize cylinder. The one case can be just old from sizing, the split in vertical in the middle of the case. Just wondering if anyone out there has had the same thing.
Thanks
