Non-lethal tranquilizer bullet

A non-lethal tranquilizer bullet, the bullet comprising:

• a housing defining an internal space, the housing including a non-penetrating distal tip disposed at a forwardmost point of the non-lethal tranquilizer bullet;
• a plunger assembly including a piston and a needle, the needle having a shaft terminating in a needle tip, the shaft having a proximal opening and a distal opening, the plunger assembly disposed within the internal space and being movable between a first retracted position and a second extended position;
• a plunger stop separate from the non-penetrating distal tip, the plunger stop extending into the internal space between the piston and the non-penetrating distal tip, the plunger stop defining the second extended position and preventing the piston from exiting the housing;
• a reservoir containing tranquilizer fluid;
• and
• a seal disposed at the non-penetrating distal tip, the seal configured to contain the reservoir of tranquilizer fluid within the internal space of the housing,
• wherein upon impact of the non-penetrating distal tip, the plunger moves from the first retracted position to the second extended position with sufficient force for the plunger assembly needle tip to puncture the seal and sufficient force for the plunger assembly piston to push the tranquilizer fluid through the proximal opening of the needle shaft and out the distal opening of the needle shaft.
