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. 

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.
