Hodgdon: new IMR Enduron powders for shooters and reloaders

The US family company Hodgdon, that celebrated its 70th birthday 3 years ago, offers a comprehensive range of new, environmentally-friendly and temperature-resistant powders. IMR Enduron series double-base, fine-grained rifle powders are blended with an ingredient originally from the military sector that reliably reduces copper fouling/tombak deposits, so that top accuracy is maintained for longer periods of time and many shots with less cleaning effort!!
