Reloder 33 shares some of the same features as Reloder 17. Reloder 33 uses the same proprietary process of impregnated kernels with burn rate control elements. This allows for a more consistent pressure curve with a delayed spike that adds as much as 150 ft./sec. over similar powders. Designed with the 338 Lapua Magnum in mind, this powder also works well with other large capacity magnums and ultra-magnums.
