Standard Range Visible Tracer rounds feature a lead-free primer, powder and tracer component. This ammunition is new production, non-corrosive, in boxer primed, reloadable brass cases.
SBR ammunition is match-grade quality and is used by top level shooters like Team Smith & Wesson's BJ Norris. Here's what BJ had to say about SBR Ammunition:
"Having fired well over 300,000 rounds during my career as a competitive pistol shooter, I have specific things I look for in ammunition. It must be accurate, consistent, and above all totally reliable. SBR Ammunition fits these descriptions perfectly. Developed and manufactured on state of the art equipment, each load goes through an exhaustive testing process before being packaged and marketed. Quality ammunition is a passion of Buddy Singleton and it shows up in every aspect of SBR's products, from the LaserMatch Tracers to the Special-Application-Subsonic rounds designed specifically for suppressors, you can trust SBR to deliver their best in every box, I know I do."
A Note from SBR on Tracer Ammunition:
Modern tracers will not "burn" your barrel out and won't cause any additional wear. The story of tracers "burning" out your barrel came from the use of corrosive based compounds in their manufacturer before the 1960. Clean your gun thoroughly with warm soapy water after firing military surplus ammunition or surplus tracer ammunition if you are not sure of the manufacturer or date of manufacturer.
