In this Diana 350 Magnum air rifle review, we’ll examine its design, barrel, trigger, sights, stock, scope rail, available calibers, and key specifications.

Diana 350 Magnum Air Rifle Overview

The Diana 350 Magnum is built around a break-barrel design with a 49.5cm barrel. Its traditional configuration includes a wooden stock, rubber recoil pad, adjustable open sights, and an 11mm scope-mounting rail.

The rifle is available in both 4.5mm (.177) and 5.5mm (.22) configurations. The supplied specifications list muzzle velocities of up to 305 m/s for the 4.5mm version and 260 m/s for the 5.5mm version. Actual performance can vary according to configuration, projectile, and applicable market restrictions.

Diana 350 Magnum Design

One of the most recognizable characteristics of the Diana 350 Magnum air rifle is its traditional sporting-rifle appearance.

The wooden stock provides a classic look and includes a rubber recoil pad. At approximately 123cm in overall length and 3.9kg in weight, the 350 Magnum is a substantial air rifle rather than a particularly compact design.

The 49.5cm barrel forms the front section of the break-barrel system, while the rear of the rifle incorporates the stock, adjustable sights, safety mechanism, and trigger assembly.

Break-Barrel System

The Diana 350 Magnum uses a tilting or break-barrel configuration. This type of system allows the barrel to pivot for loading before returning to its firing position.

Break-barrel air rifles are mechanically straightforward compared with PCP platforms because they do not require an external compressed-air reservoir. Their operating characteristics are therefore different from those of pre-charged pneumatic air rifles.

Diana 350 Magnum Trigger

The rifle is equipped with a match-type trigger. Trigger design is an important consideration in an air rifle because it influences the feel and control of the firing sequence.

The 350 Magnum also incorporates an automatic safety system, providing an additional safety feature within the rifle’s operating mechanism.

Adjustable Sights and Scope Rail

The Diana 350 Magnum comes with adjustable open sights. The supplied specification describes the sights as interchangeable and adjustable, providing flexibility when using the rifle’s open-sight configuration.

An 11mm rail is also incorporated for compatible scope-mounting equipment. This allows the rifle to accommodate an appropriate optical setup where permitted and suitable.

Diana Air Rifle .177 Configuration

The Diana air rifle .177 configuration uses the 4.5mm caliber. The supplied specifications list a maximum muzzle velocity of approximately 305 m/s for the 4.5mm version.

Velocity figures should not be interpreted as universal performance figures because results can depend on factors including pellet weight, rifle configuration, environmental conditions, and local specifications.

The .177 caliber is widely used within the airgun category, particularly for target and recreational shooting applications where permitted.

Diana 350 Magnum 5.5mm Configuration

The alternative 5.5mm configuration corresponds to the .22 caliber. The supplied specifications list a muzzle velocity of approximately 260 m/s.

The larger caliber provides a different projectile configuration from the .177 version, meaning that caliber selection should be considered alongside the intended lawful application and the manufacturer’s specifications.

Diana Air Rifles and Build Quality

Diana has a long history in the airgun industry, and the 350 Magnum reflects the company’s traditional approach to sporting-air-rifle design.

Its combination of a wooden stock, adjustable sights, break-barrel action, match-type trigger, and scope rail creates a conventional configuration. The design is notably different from modern PCP rifles that typically emphasize compressed-air reservoirs, regulators, and multi-shot magazine systems.

The term “most powerful Diana air rifle” is often used in searches comparing different Diana models. However, power depends on the specific model, caliber, configuration, and market.

Rather than describing one model as universally the most powerful, it is more accurate to compare manufacturer specifications and the legal power limits applicable in the relevant jurisdiction.

The Diana 350 Magnum is designed as a substantial magnum-class spring-piston air rifle, but published velocity alone does not provide a complete measure of performance. Pellet weight and other variables also influence muzzle energy and ballistic characteristics.
