I ended up buying MagTech 98 grain .32 S&W long wadcutters as bulk ammo, hoping they won't be too dirty or lead up the revolver something fierce. I avoided the PPU lead ammo because I've experienced their .38 lead ammo in my Performance Center 686 with hideous leading being the result.
I ordered the Lost River polycoat wadcutters as carry ammo.
If somebody would have told me a couple years ago that I'd be buying 700 rounds of .32 ammo for a wait-listed J frame I'd have said they were on crack.
