IMR 4350 Smokeless Gun Powder

Production of IMR Powders dates back over 200 years when the company was originally founded by E.I DuPont. Available for use in many reloading applications, the IMR series of powder is trusted by reloaders all across the globe. An extruded powder, IMR 4350 is primarily used for the newest short magnum cartridges in the industry but also used for silhouette shooting. Also for magnums with light to medium bullet weights, IMR 4350 is the best choice.

Long-Range & Magnum Performance You Can Trust

Bring home the trophy or win the match with IMR 4350, a time-tested, medium-slow burning rifle powder favored by hunters and long-range shooters. IMR 4350 provides the high muzzle energy and stable velocities needed for cartridges like .270 Win, .30-06, .300 Win Mag, and many belted magnums. Expect flatter trajectories, strong terminal performance, and repeatable downrange results so you can make the shot that counts when it matters most.

Stable Ballistics & Clean Combustion

Accuracy begins with consistency. IMR 4350 produces tight standard deviations and predictable pressure curves, which translates to smaller vertical dispersion and easier zero maintenance. Its modern formulation also promotes cleaner combustion than older slow powders, reducing copper and carbon fouling so your barrel stays truer over long strings of fire. The result: more time shooting and less time cleaning.

Reloading Efficiency Metering & Case-Fill Benefits

Reloaders appreciate IMR 4350’s excellent flow characteristics for an extruded powder: it meters smoothly through measures, works reliably on both single-stage and progressive presses, and offers predictable lot-to-lot consistency. IMR 4350 also provides efficient case fill in larger rifle cartridges, allowing you to reach desired velocities without harsh pressure spikes. That makes load development straightforward and repeatable.

Temperature Resilience & Real-World Reliability

Whether you’re glassing in cold mountain mornings or hunting in late-summer heat, IMR 4350 delivers reliable ignition and stable performance across normal shooting temperatures. That temperature resilience gives you confidence that your handloads will behave like the data predicts essential for ethical hunting and accurate long-range shooting.
