Milsurp tracer rounds

[SSBotanyBay]

Whilst wandering through the local gouger mountain I came across an ammo can of 5.56 so I purchased it and quickly discovered that they were in fact tracer rounds (I knew that at time of purchase though the implications of such a purchase had not yet settled in). I am having a difficult time finding much definitive info on the round itself in regards to its accuracy vs. non-tracer rounds, the impact they have on barrels, and whether or not this stuff still "traces" after sitting for so long. Can yall school me on this stuff? Should I just sell it and save myself the trouble?

Tracers don't light until after they have left the barrel. Typically if a batch is past it's expiration for lighting it says so when you are buying them. ARF has a ton of threads on them.

also a note......most ranges wont let you shoot them due to fire hazards. if you shoot them on private property, be aware of what you are shooting at and that it could start on fire. They sure are fun though
