Piney Mountain .22LR tracer ammunition by Exotic Firearms produces a bright colored beam of light over 100 meters. 

The .22LR tracers are non-corrosive, so they don’t hurt your barrel.  Unlike most .22LR tracers, these are hollowed out in the back so the tracer chemicals never make contact with the barrel.  Piney Mountain .22LR tracers are the most inexpensive tracers on the market and have an almost perfect light rate. These tracers are designed to work with any .22LR.
