Reading the 115gn/9 mm Luger thread, it started me thinking about the ammo that I have loaded and what it consists of. I have loaded a lot of rounds which are Berry’s plated bullets. I think they are all 9 mm but I can’t be sure until I go dig through my ammo chest. But from what I’m reading, it sounds like plated bullets should never be used in certain firearms (or certain types of firearms) and interests me greatly to know which and why. What features of a firearm would make using a plated lead bullet a poor idea? Do any particular folks have blanket recommendations against plated bullets?
