Lets talk airguns.I recently googled napier pro hunter pellets.They lube there pellets. The lube they use increases speed due to the fact that it is gassing off.

I call this pellet doping.I've experimented with this for 2years.Amazing results without any problems.

Soory if you play with this and have no PAL and you get caught by the law YU ARE IN DEEP CRAP.

Anyone else play with this concept.
