RBCD Performance Plus, Inc.
One company, RBCD Performance Plus, Inc. of San Antonio, Texas, produces ammunition marketed as blended-metal bullets. However, RBCD's "Blended-Metal Technology" (BMT) is a trademark and not a description of bullet composition. Independent testing by Gary Roberts showed that RBCD ammunition is, "nothing but lightweight, repackaged varmint bullets disguised with a black coating of moly, and driven to higher than normal velocities with concomitantly higher than normal pressures." Roberts cites a USSOCOM and ARDEC study published in 2007 which supports his findings.
