I'm pretty green regarding reloading and was wondering a few things; 1. Why do some of the commercial wc loads have a serrated band around the center of the shell and others don't? 2. Some wc double flatended bullets are completely inside the shell and others are sticking out about 1/4"? 3. I'd like to develope a wc load using a 148grn double flatended bullet in .38 if I load with the whole bullet inside do I need to adjust for pressures? 4 What is a bb wc ? what other kinds of wc's are there? 5. can you use standard(Lee) dies to load wc's ? Thank you for any help you can give.
