Lee Precision New Auto Prime is a hand priming unit. The priming tool and components are all in good condition. The kit is in a form box with four (4) different shell holders. It is complete with small and large priming units and primer tray. It primes both small and large cases both pistol and rifle. The shell holders are #1 for ,38spl/.357 and the #4 is for .223 and .380 ACP with many more calibers, and #6 I have used on some 9mm cases that have a small base head. Any questions or other info just give me a call.
