Also known as: RWS 350 Magnum, RWS Diana 350 Magnum, Diana 350 Magnum Classic
Overview
The Diana 350 Magnum is a German break-barrel, spring-piston air rifle built by Mayer & Grammelspacher (Diana) of Rastatt, Germany. A single-shot magnum-class springer offered in .22 (5.5mm) and .177 (4.5mm), it is one of the most powerful conventional spring-piston rifles ever mass-produced, driving .22 pellets to roughly 20-22 ft-lbf of muzzle energy. Cocked by breaking the rifled barrel, it uses the adjustable Diana T06 two-stage trigger, a Monte Carlo beechwood stock usable by left- or right-handed shooters, fiber-optic open sights and an 11mm dovetail rail for scope mounting. Its high power comes at the cost of a heavy, roughly 45-pound cocking effort and noticeable recoil, making it a favorite for hunting and long-range plinking.

Background
Diana, founded in 1890 in Rastatt, Germany, is one of the oldest airgun makers in the world. The 350 Magnum became the company's flagship high-power break-barrel, prized among airgun hunters for wringing near the practical ceiling of spring-piston output while retaining the refined T06 trigger and traditional beechwood stock that define the Diana line.
