These ultra-bright tracers are brand new production from the #1 hot tracer company, Piney Mountain. Available in red and green color, they burn for over 400 yards and are now available to load by yourself! Free shipping offered on both 1000rd and 250rd packs. They utilize a hollow based bullet that contains a pyrotechnic composition similar to a flare. When fired , the smokeless powder in the cartridge ignites the tracer composition. They are non corrosive and will not harm your barrel or firearm.
Consistent burning pistol powders like HP-38, Titegroup, and Winchester 231 have all been tested to ignite these reliably. This tracer after production yields a ~120gr projectile and should be loaded to 1,100FPS for maximum effectiveness.
