Lee Auto Prime Shell Holder #4 securely grips .223 Remington, .204 Ruger, and .17 Remington cases for hand priming operations with the Auto Prime tool.
The Lee Auto Prime Shell Holder #4 is a precision-engineered component designed for reloaders who prefer the control and simplicity of hand priming. This shell holder is specifically sized to accommodate popular rifle cartridges including .223 Remington, .204 Ruger, and .17 Remington.
This is shell holder size #4 only. Lee manufactures 20 different shell holder sizes to cover virtually every modern cartridge. If you reload multiple calibers, consider the Lee Shell Holder Kit, which includes 11 popular sizes covering over 115 different cartridges.
Many experienced reloaders prefer hand priming because it gives you direct tactile feedback about case condition and primer seating. The Auto Prime system makes this process efficient and repeatable, and this shell holder is the foundation of that system.
