About
What it is, and why it matters
The FX Dynamic is a regulated pre-charged pneumatic (PCP) air rifle built by Swedish maker FX Airguns on an aluminum chassis. It carries a 480cc carbon fiber air bottle integrated into the butt stock, an AMP MKII regulator, and a plenum-over-barrel design of up to 156cc for high, consistent power. Offered in .177, .22, .25, .30 and .35 calibers with FullPower and Sub12FPE tunes, it feeds from a removable rotary magazine and mounts on a modular Arca and M-Lok platform aimed at hunters and long-range airgun target shooters.
FX Airguns was founded by Fredrik Axelsson in Sweden in 1999 and became known for its Smooth Twist barrels and modular, tunable PCP platforms that dominate international field target and extreme long-range airgun competition.
Sold in Express (500/600/700mm barrel), Compact and VP (value package) configurations. Power is externally adjustable; the .35 caliber option can reach roughly 200 ft-lbs (about 270 J).

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.
