It performs admirably in cartridges such as the 300 Winchester Magnum, 7mm Remington Magnum, 338 Lapua, and a variety of others. Loading density is ideal for magnums, filling the case nicely at maximum charges and contributing to excellent uniformity and accuracy. The 7mm Remington Magnum has “never had it so good!”

  • Keep the loads in the reloaders guide no higher than what is specified.
  • There should never be any mixing of two powders, regardless of their type, brand, or source.
