Improving accuracy begins with consistency and no reloading process offers a better return on investment than turning eccentric case necks to a uniform wall thickness. At the moment of ignition, the brass must expand evenly to ensure proper bullet release. When brass thickness varies, the thinner side releases the bullet prematurely, creating a slight bullet-to-bore misalignment that can significantly impact accuracy. The standard Case Holder (vise) included with the HOT100 is designed for cases with rims up to .592 inches. For larger cases, a Large Case Holder is required, accommodating rims between .593 inches and .812 inches in diameter. By addressing inconsistencies in brass thickness, this precision-focused tool helps reloaders achieve unparalleled accuracy and consistency.
