Powder Valley Expects New Alliant Powders by Mid-September
In related news, Bryan at Powder Valley let us know that two new Alliant powders should arrive very soon: “We expect to receive Alliant Reloder 33 and Alliant 1200R within the next 10 days. Alliant RL33 was specifically manufactured for the 338 Lapua Magnum. Alliant 1200R is a new ball powder very similar to Reloder 10X.” This would make Allliant 1200R a good choice for progressive reloading for small rifle cartridges. Powders in the RL10X burn-rate range work well for light bullet applications in .222 Rem, .223 Rem, .22-250 Rem and benchrest calibers.

New Reloder 33 Delivers More Speed in Big Magnums
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. Reloder 33 should “raise the bar” of velocity for the .338 Lapua Magnum and other ultra-magnums.
