Reloaders who demand high performance choose IMR smokeless powder
The IMR brand was created under the DuPont Corporation. In fact, E. I. duPont arrived in America in 1800 determined to make an improved gunpowder and, by 1802, was producing gunpowder in a new plant along the Brandywine River in Wilmington, Delaware (this plant morphed into what is today the GOEX brand of black powder).
DuPont had historically been a major supplier of military propellants long before becoming one of the handloader’s favorite powders. First used in battle in 1805 by United States naval forces against pirates off the coast of Algiers, DuPont supplied more than 80% of Allied Forces powder needs in World War I. Every week of WW II, as many munitions were used as in all of WW I. This demand lead to an incredible 2.5 billion pounds of smokeless propellants being manufactured by DuPont for Allied Forces in World War II.
The IMR brand was first introduced under DuPont in the 1930’s. IMR is an acronym for Improved Military Rifle. The first IMR reloading powders included ever popular favorites IMR3031 (1934), IMR4064 (1935) and IMR4350 (1940). Each of these are still favorites with handloaders today! The IMR series of handloading powders were the only choice to wring full performance out of rifle calibers. For this reason, the IMR brand powders truly are Legendary products.
Time does not stand still and neither does the IMR brand. Although the brand continues to be a favorite of handloaders everywhere, new technology has allowed improved versions of the traditional IMR burn speeds to be introduced. These improved powders, identified by the “Enduron” sub-branding, offer improved temperature stability and an additive that removes copper bullet jacket fouling as you shoot. The Enduron powders are the first to offer all these features at the same time. The Enduron powder line continues to bring new burn rate offerings to the handloader.
Even in the early days, DuPont focused on innovation – offering “any quantity of powder as good or better than any available”. Today, IMR is still focused on innovation. Originally a line of rifle powders the IMR brand has been expanded to include powders for use in handgun, shotshell and muzzleloaders. For 2017, IMR introduced five new pistol and shotshell powders. The IMR brand commitment to bring new and legendary powders to the handloader is a never-ending process.
In 2003, Hodgdon Powder Company acquired the IMR brand bringing these prestigious powders under the umbrella that also includes Hodgdon, Winchester, Accurate, Blackhorn 209, Ramshot, and more. Any gunpowder required by handloaders can be sourced through these brands.
New Enduron Powders from IMR
It’s always exciting to see new reloading products that make things “that much better”. That was my first impression when trying Hodgdon’s CFE 223 and CFE-Pistol powders. These powders have performed great, and I love the fact that copper de-fouling is “built in”. There’s a new crop of powders from IMR that feature copper de-fouling plus extreme temperature stability (great performance over a wide range of temperatures), and “green” (environmentally responsible) production. They are the new “Enduron” line of powders.
I’m thinking these powders will offer an interesting comparison for 6.5 Creedmoor and 243 Winchester for the Ruger Precision Rifle project I’m working on. Look for Enduron features in these and other blog series over the next year! Are you loading and shooting Enduron? Please share your experiences!
FAQS IMR SMOKELESS POWDER
WILL ALL YOUR IMR POWDERS BE READILY AVAILABLE?
While there are some exceptions such as our Enduron and Trail Boss powders, the majority of our powders will be easily located via various retailers.
WHY CAN’T HODGDON MAKE MORE POWDER?
We wish it were that simple – what we have experienced since 2020 is a demand issue and not a supply issue. The reality is we are doing everything possible to maximize shipments to our customers, including running overtime in production, packaging and shipping areas and working with our shipping partners to add new inbound and outbound shipping options. During the past 3 years, we broke record after record for powder shipments. We learned what worked best in terms of distribution and will continue to maximize all efforts to maintain this high level of shipping.
WILL HODGDON BUILD ANOTHER PLANT TO KEEP UP WITH FUTURE SPIKES IN
DEMAND?
A new powder production facility would require an investment far beyond our finances and no financial institution would finance this type of building project. While the past 3 years of demand appears to be different from demand spikes in the last 20 years, the “normal” powder demand for the U.S. would not support an additional manufacturing plant. Most companies cannot afford to build a new production facility and then have it set idle until demand spikes. An additional complicating factor would be locating this plant – there are only a handful of these facilities in North America and none have been built in the last 30 years.
WHY IS HODGDON SELLING POWDER TO AMMUNITION MANUFACTURERS?
Our focus is the handloading enthusiast. Yes, we sell some powder to strategic, mostly smaller ammunition manufacturers, but that is a small part of our business. The heart of our business is smokeless powder for the handloading enthusiast. Every day, we receive calls from potential OEM customers who are looking for powder to load in ammunition. Every day, we politely decline this new business so we can focus on our long-term customers and sales channels and most importantly, our costumers who have supported us for decades.
WHY IS HODGDON SELLING POWDER ON AUCTION SITES?
Hodgdon does not sell powder on any online auction sites. We sell through traditional sales channels to wholesalers, retailers and dealer customers. While we recently began selling direct-to-consumer on our own websites, we prioritize our shipments to our traditional sales channels to maximize powder availability at sporting goods and gun shops everywhere.
