About
What it is, and why it matters
The Benjamin Bulldog is an American big-bore pre-charged pneumatic (PCP) air rifle produced by Crosman under the Benjamin brand. Built in a compact bullpup layout around a rifled Lothar Walther steel barrel, it fires .357 caliber (9mm) slugs from a five-shot rotary-style magazine and a 3000 psi air reservoir. The original model delivers up to roughly 800 fps and around 200 foot-pounds of energy, while the later M357 version reaches up to 1135 fps and about 300 foot-pounds. A baffle-less SoundTrap shroud reduces the report, and a 26-inch Picatinny rail, adjustable two-stage trigger and synthetic stock make it a popular hunting and pest-control air rifle for game up to hog size.
When it launched in 2015, the Bulldog became one of the first affordable big-bore bullpup air rifles, bringing .357 caliber PCP hunting power to a mainstream price point and helping popularize big-bore airgun hunting in the United States.
Also offered in .457 caliber. The updated M357 raises muzzle energy to about 300 ft-lbs versus the original's roughly 180-200 ft-lbs. Muzzle velocity and energy vary widely with slug weight; the platform typically yields about 5 useful full-power shots per fill.

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.
