Alliant

Alliant's Reloder 33 uses the same kernel-impregnation technology first pioneered in Reloder 17. It 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. 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.
