SHOT Show: New Reloder 33 and Power Pro 1000 from Alliant

When Alliant’s Reloder 17 was introduced, it represented a real break-though in propellant technology. In some cartridges, Reloder 17 delivered significantly more velocity than any other propellant on the market. The secret was a new method of impregnating the powder kernels with burn-controlling compounds. This delayed the initial pressure spike, allowing a longer, more constant powder burn. This effectively delivered more energy over the powder’s full burn cycle, and the extra energy produced higher velocities than could be attained with conventional powders.

Alliant Reloder 33New Reloder 33 Delivers More Speed in Big Magnums
Now Alliant is introducing a new powder, Reloder 33, that uses the same kernel-impregnation technology first pioneered in Reloder 17. Alliant Reloder 33 is a new powder created by Rheinmetall Nitrochemie in Switzerland (Nitrochemie also makes Reloder 17). Like Reloder 17, Alliant’s new Reloder 33 powder employs a proprietary process by which the powder kernels are impregnated with burn-rate controlling elements. This delays the peak pressure spike and smooths out the pressure curve. Effectively, this allows the powder to deliver energy at a more constant rate, producing more overall velocity for the bullet — as much as 150 fps more than with any other powder. Reloder 33 was designed for the .338 Lapua Magnum but it is suitable for other large magnums and ultra-magnums.

In this video, Allliant’s Dick Quesenberry explains the properties of Reloder 33, noting that it should “raise the bar” of velocity for the .338 Lapua Magnum and other ultra-magnums. Outstanding velocities have been achieved in initial tests with the .338 LM. This has attracted the interest of the U.S. Military, which has already placed orders for Reloder 33 in bulk. Reloder 33 should hit the consumer market in mid-April to mid-May, the actual release date depending on DOT transport certification. Expect vendors to have the new powder in stock by the end of May, if not sooner.

Power Pro 1000 for High-Volume Reloaders
In addition to Reloder 33, Alliant is introducing Power Pro 1000. This is a new spherical (ball) powder with a burn rate similar to Alliant 10X. Power Pro 1000 is designs for varmint shooters and .223 Rem shooters who load large quantities of ammo on progressive presses. Power Pro 1000 meters exceptionally well through progressive press powder measures, and it should provide good load density in cartridges such as the .223 Remington. Alliant hopes to release Power Pro 1000 in early- to mid-April.

Euro Powder-Maker Shares Technology with ATK (Alliant), Plans Joint Production in USA

Alliant Reloder 17If you have followed our reports on Reloder 17, you’ll know that this Alliant powder, produced in Europe by Rheinmetall Nitrochemie, is a unique propellant that, in many cartridges, can offer 100 fps (or more ) velocity than any other commercial powders. The secret to the extra speed is a proprietary Nitrochemie process that embeds or saturates the kernels with burn-rate controlling compounds. This allows a longer duration, extended energy release. Most conventional extruded powders have surface coatings only. These tend to have a strong “spike” in their energy release but then decrease rapidly in energy output. By sustaining the energy release over a longer period of time (in the barrel), powders such as Reloder 17 promise to deliver higher velocities than could be achieved with other propellants.

Following the release of Reloder 17, sources at Alliant Powder, an Alliant Techsystems (ATK) subsidiary, confirmed that we can expect more powder products using the new Nitrochemie technology. Alliant plans to release both a faster powder (for 223-sized cartridges) and a slower powder (for large magnums).

ATK and Rheinmetall Nitrochemie Announce Strategic Partnership
Rheinmetall Nitrochemie (RN) is jointly owned by Rheinmetall AG and RUAG of Switzerland. Since 2005, ATK has been a Rheinmetall sales partner. Now ATK and Rheinmetall Nitrochemie plan a much closer relationship, through which RN will share propellant technologies and ATK and RN will produce powders together in US facilities. ATK has agreed to a “strategic partnership” with the Rheinmetall Nitrochemie Group, the propellants division of the Düsseldorf-based Rheinmetall Defence Group.

According to DefenseNews.com, “Under terms of the agreement, propellant technologies will be transferred from Nitrochemie to ATK, and the two companies will target sales in North America and elsewhere. While Rheinmetall will gain access to expanded markets, ATK will receive licenses to manufacture and sell powder and propellant systems developed by the German firm. These products will be marketed to both the U.S. military and other ammunition manufacturers.” Through the strategic partnership, ATK will become the exclusive North American vendor of the new-generation Nitrochemie propellants. The technology transfer positions ATK as the exclusive North American provider of Nitrochemie’s Extruded Impregnated (EI), Extruded Composite Low-sensitivity (ECL), Surface Coated Double Base (SCDB), and R-Type propellants.

Rheinmetall Nitrochemie to Build Powder-Making Facility in the USA
As part of the new, expanded business relationship with ATK, Rheinmetall Nitrochemie will shift some of its actual powder production to the United States. Rheinmetall and ATK revealed “medium-term plans” under which a new, powder-processing plant will be set up in the USA and operated by Rheinmetall Nitrochemie in cooperation with ATK. This will allow Nitrochemie propellants to be sold at more competitive prices, since they will no longer have to be shipped across the Atlantic. No specific date was given for the construction of the new powder factory.
