IMR powder production dates back more than 200 years, when E.I. DuPont founded the company. The IMR series of powder is trusted by reloaders all over the world and is suitable for a wide range of reloading applications.
IMR 4198 is a fast-burning rifle powder that performs admirably in cartridges such as the 222 Remington, 221 Fireball, 45-70, and 450 Marlin. It’s a favorite among varmint shooters who use small-bore cartridges. Proven metering and other necessary elements were included to make it extremely insensitive to hot/cold temperatures. IMR 4198 performs admirably in cartridges such as the 222 Remington, 444 Marlin, and 7.62 X 39.
