The Absolute Hammer is specific ogive design, that falls under our PDR patent, eliminating any engraving by the rifling forward of the shoulder of the bullet. This bullet will not engage the lands anywhere on the ogive. This eliminates distortion of the nose that causes changes in bc from rifle to rifle depending on how loose or tight the bore is. The bonus to this design is greatly reduced engraving pressure resulting in significant gains in velocity compared to bullets of the same weight. In our 280ai test rifles we gained 300-400 fps over conventional bullets of the same weight. Given the low pressure and extra velocity these bullets produce, they should only be loaded by experienced hand loaders that are very good at reading pressure signs. You will see that these bullets will require faster than normal powders for the cartridge and bullet weight. Load with caution.
