About
What it is, and why it matters
The Benjamin Maximus is a single-shot, bolt-action pre-charged pneumatic (PCP) air rifle chambered for .22 caliber pellets. Introduced by Crosman under its Benjamin brand in 2016, it was marketed as the first sub-$200 PCP air rifle, using an accessible 2,000 psi fill pressure and an onboard manometer to deliver roughly 20 to 30 shots per charge from its rifled steel barrel and synthetic stock.
Launched as the airgun that broke the price barrier for pre-charged pneumatics, the Maximus made PCP shooting affordable to hunters and plinkers who previously could not justify the cost of a high-pressure fill setup.
Also offered in .177 caliber, which reaches about 1,000 fps versus roughly 850 fps in .22. A hand pump makes the low 2,000 psi fill practical without a scuba tank or compressor.

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.
