Thanks again everyone for the help. Went to the range today and tested the first batch of 50. Worked extremely well, definitely hooked now. I ended up crimping at the first groove and downed the max charge of HP-38 from 3.7 grains to 3.3. No leading that I could see afterwards (maybe a little streak that could have been there for years until I over analyzed it.)
For the record, I'm totally not a bullseye shooter... More of a minute of letter paper at 10 yards shooter... ;-)
