Please forgive me if this question has been beat to death here. I'm getting, in my opinion, a huge amount of left over flakes of powder in my DW Vigil after shooting my reloads. I'm brand new in reloading. Using Xtreme 200gr. plated bullets, with HP-38 powder. I loaded various different amounts of powder from 5.0 to 5.4 grains. Although I do like the accuracy, for me anyway, I am getting an unacceptable amount of left over flakes of powder with each load. COL I tried to keep as close to 1.255-1.260. I'm thinking that this COL could be on the too long side? Any suggestions from the people here that are way more experienced than I would be greatly appreciated.
