.243 WSSM Neck Sizing Die Only

This is an RCBS 243 WSSM caliber Neck Sizing Die only. A neck sizing die allows the reloader to properly size the case neck just enough to snuglly hold the bullet for optimal bullet tension, while maintaining the fire-formed dimension of the case body. Accuracy is increased when the case body closely fits into the chamber. By not overworking the brass, this RCBS Neck Sizing Die produces superior accuracy and extends the life of expensive cases. Neck sizing with this die can eliminate problems of excessive head space and align the bullt perfectly with the bore, resulting in better accuracy and longer case life.
