The M 52 was not really designed for plated or jacketed bullets.
Unless you have no choice and are shooting in a lead free zone.
I understand that, but I need to avoid smoke for alergenic reasons. I have the gun and want to shoot it with less side affects. S&W used a basic 9mm barrel to creat this target gun and 356 bullets have performed well for me. I also have an original Star Sizer that I'm trying to justify keeping. Just thinking out lowd here. Thanks for your reply!
