About
What it is, and why it matters
The Mossberg 535 ATS (All-Terrain Shotgun) is a pump-action 12 gauge shotgun introduced in 2005, built on Mossberg's proven 500-series platform but chambered for 3.5-inch magnum shells. It retains the signature ambidextrous top-tang safety and twin action bars of the 500 family and is sold in field, turkey, waterfowl, and combo configurations, the latter packaging both a vent-rib smoothbore barrel and a fully rifled slug barrel.
The 535 ATS stretches the legendary Mossberg 500 action to swallow 3.5-inch magnum shells, and its combo packages ship with two barrels, a vent-rib smoothbore for birdshot and a fully rifled tube for slugs, so a deer hunter and a duck hunter can share one receiver.
Essentially a 3.5-inch-chambered evolution of the Mossberg 500. Combo packages include interchangeable smoothbore and rifled barrels for shot and slug use.

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.
