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 4227 is the Magnum Pistol Powder in the IMR lineup. If it says Magnum, IMR 4227 is the choice for true magnum velocities and performance. In rifles, this powder delivers excellent velocity and accuracy in such cartridges as the 22 Hornet and 221 Fireball.
With loading anything in the shotgun you have to follow a published recipe in a manual. Every item in the recipe has to be used without any substitution. The geometric dimensions of 4227 allow it to stay in the correct position in the case (hull) better than most It does not migrate into the wad cavities if you use a wad compatible with the case. As with all shotgun reloads you need to check them as time goes by. Powder migration shows up as a sunken in the crimp. If you find it on your loads just cut one open. You will probably need to cut all of them open and reclaim your components excluding wads.
