My plinking loads are typically 38 Special 158gr jacketed RNFP ammo and similar bullet in 357 Magnum.

Source I've been using Freedom Munitions for most of my ammo requirements. Good selection of 38s but 357 is waiting on bullets.

Good source of new, reman and cosmetic flawed blaster grade ammo. Never had any issues with any of it and I typically buy reman or blaster grade ammo.
