Product Overview: IMR 4227
When E.I. DuPont created the corporation more than 200 years ago, he began manufacturing IMR 4227 for sale in stock for use in many applications. The IMR 4227 line of powder is trusted by reloaders all over the world because it is versatile and may be used in a variety of reloading situations.
It is IMR 4227, the Magnum Pistol Powder, that is available in the IMR portfolio. Whenever the word Magnum is mentioned, the IMR 4227 is the preferred choice for true magnum velocities and performance. The 22 Hornet and 221 Fireball cartridges, among others, benefit from this powder’s high velocity and accuracy when fired from rifles.
