A: Thanks for reaching out Shotgun! There are two major types of full metal jacket (FMJ) bullets: plated, and jacketed. A plated bullet begins as a lead core. It is plated with copper via electrolysis. A plated bullet's core is totally enveloped by its jacket, which prevents the heat of ignition from vaporizing lead off its core. That promotes a cleaner barrel and limits the shooter's exposure to lead. A jacketed bullet starts off as a copper cup, which is formed into the shape of a jacket. Lead is then swaged into the jacket to create the core. A jacketed bullet is compatible with ported barrels and compensators, and can withstand acceleration to higher velocities (aka magnum velocities). A jacketed bullet also emits aerosolized lead during ignition.

A: Hello Scott!
The Blazer brass ammunition uses a copper plated, lead core projectile. This specific round does not contain any steel in the projectile at all.
