Lyman's Universal Spring Loaded Decap Die is equipped with a spring-loaded decapping rod system that ensures the primer is forcefully ejected from the primer pocket every time. This die works great for processing brass on automated and progressive presses, as well as for prepping brass for cleaning on standard turret and single station presses. Works on all calibers 22 through 45 except for 378 and 460 Weatherby. (Will not remove Berdan primers.)
