Hodgdon CFE-BLK was designed to provide that level of consistency and performance in the.
Such loads tend to deliver more consistent performance, resulting in fewer muzzle velocity variations between each shot.
300 Blackout.Īn optimal powder charge fills up between 90% and 100% of the case, provided it doesn’t result in dangerous levels of overpressure. 223 Remington, CFE Pistol is best suited for commonly-used pistol cartridges (9x19mm. Serving as optimal powders for their intended cartridges.įor example, CFE-223 is optimized for.Reducing copper fouling in the barrel even after high volumes of fire.It was later followed by CFE Pistol in 2014 and CFE BLK in 2019.Īll CFE powders are double-base, spherical propellants designed to perform 2 tasks: In 2012, Hodgdon introduced the Copper Fouling Elimination reloading powder line, with the CFE 223.

IMR 4227 is suitable for supersonic and subsonic loads. The relatively fast burn rate makes it suitable for loading various varmint and intermediate rifle cartridges with limited case capacity, such as. It is a classic reloading powder that should be on the shelves of any handloading enthusiast. IMR 4227 is a pistol powder with a medium burn rate, primarily intended for use in Magnum pistol and revolver cartridges. Today, IMR is a trademark of the IMR Powder Company, a Hodgdon brand. IMR propellants have long been used to manufacture US military service ammunition, such as. DuPont initially developed the first Improved Military Rifle (IMR) powders between World War I and World War II as miniaturized versions of US artillery extruded propellants.
