About
What it is, and why it matters
The Evanix Rex-P is a South Korean pre-charged pneumatic (PCP) air pistol built around an unusual cocking system in which the trigger guard doubles as an underlever, opening the breech and cocking the action in a single stroke. This compact single-shot pistol feeds a rifled barrel from a detachable air cylinder fitted with an integrated pressure gauge, and is offered in .22, .25 and .357 calibre. In .25 it delivers roughly 37 ft-lb of muzzle energy at around 810 fps, making it a capable small-game and pest-control airgun in a highly portable package.
Marketed as the Rex-P pellet pistol; the same Rex action is also offered in a full-length rifle configuration. Air cylinder detaches for transport, storage and refill.

Trajectory
What the round does downrange
Solved from the muzzle figures and the bullet. The dashed rule is the effective range on the record, and the crosses are the steps the solver returned.
No load solved for this record yetThe flight path is computed from a cartridge and a bullet. This record has no ammunition filed against its chambering, so there is nothing to solve.
