Wax bullet

Specially designed cartridges and conversion kits can be used together to convert semi-/fully automatic firearms into wax bullet guns, used in tactical training for police and military.

This practice goes back at least as far as Jean Eugène Robert-Houdin, who used hollow wax bullets colored to resemble lead balls.

The optional addition of beeswax and/or grease will produce a softer, more flexible bullet than pure paraffin.

The World Fast Draw Association uses wax bullets in many of their competitions, along with special "balloon popping" blanks that fire coarsely ground gunpowder.

The sport first gained popularity in France where in 1901 Dr Paul Devillers, who was also a keen ‘duellist’, designed a new innovative wax bullet for duelling practice.

Wax bullets are normally used only in revolvers and single shot pistols for short range target practice.

Simunitions (for "simulated munitions") are special cartridges that fire colored paint-filled plastic projectiles which are used to mark targets much like paintballs.

The paint-filled plastic projectiles are more durable and accurate than paintballs, and it is safe to be shot by them when wearing protective clothing.
