Ditch the Dillon cup. How many times have you spilled a full cup of spent primers on the floor? Isn't it about time to stop doing that?
Our primer drop adapter bolts to the 1050 where the stock bracket is that holds the cup. Remove the bracket, and use the existing screw to attach our primer drop adapter. Slide on a 3/8" ID clear vinyl hose from your favorite local hardware store and never drop that silly cup again.
