Prior to reloading, some hulls may require a little reshaping of the hull mouth. Some hulls retain a very strong crimp memory and will only partially open after being fired. Other times, dents or crimp creases limit a fresh, new crimp during the loading process. Sometimes you just need a fresh crimping surface - and that's what the Spin Doctor provides.

The Spin Doctor's special shape, when combined with heat generated by rotational friction, gently reconditions damaged hulls. The tool reshapes the crimp mouth by reforming the shrunken plastic mouth and smoothing rippled plastic. Fits in any standard hand drill or drill press.

The Spin Doctor saves the cost of hulls that would have otherwise been discarded; returns factory-sharp crimps.
