Congrats Brad-you never forget the first 3 ringer. I still get excited digging one after finding between 2,000-3,000 CW bullets. As Old River said, you can wash them under water. I use an old soft bristle toothbrush to get the dirt from between the rings. Do so gently. I use the clip part of an old plastic pen to clean the cavity.
I have found only one French Triangle bullet in 15 years of CW relic hunting. They are purely CS used and relic dealers sell them fot $25 in dropped condition. I hope you dig many more CW bullets. WTG and HH, Quindy.
