The patented Universal Loading Tray, redesigned to replace the long-serving LT-150, is built to accommodate a wide range of ammunition types. It supports rifle calibers from .17 through .458, as well as common handgun calibers such as 9mm, .38, and .45. In addition to these standard rounds, the updated design also accommodates newer and larger cartridges, including WSM, WSSM, Remington Ultra Magnum, and the .500 S&W Magnum, making it a highly versatile tool for reloaders.
