Case Slick is an exlusive formulation that provides exceptional lubricity for resizing or forming of metallic rifle and pistol cases. Testing reveals, Case Slick reduces the force needed to resize 308 Winchester cases by 35 to 70 percent when compared to other spray lubes. Reducing the resizing force makes the process easier on you and your brass. Case Slick is formulated to flow evenly over the surface of the brass. Uniform coverage makes resizing a breeze and eliminates the possibility of denting the shoulder of the case.
