Thinking back to when I started reloading (long time now- my oldest kid was riding her first tricycle then, and now she's flying for the Marines) ... I started with jacketed bullets with a cannelure for 38's..... count yourself lucky that you have this forum.... I had very little information to work with besides a single reloading manual, and nobody wanted to help a new guy out.
Once I had the process down, I went to loading 38's with plated 125gr bullets (Ranier and Berry's) because they were much more economical .... I fired just one box of lead round nose factory bullets .... they dirtied up the gun so bad I swore I'd never put another lead bullet in any of my guns...... plated run cleaner, and at 38 special velocities, there's no good reason to use jacketed bullets. Recoil isn't harsh enough to require a heavy crimp, anyway, and it takes a REALLY heavy crimp to cut through the plating. I've never bothered to try the powder coated bullets- not worth my time to work up new loads by changing anything ..... still running Berry's 125's over red dot.
