The RCBS Auto Primer Feed Tube for Small Primers streamlines primer handling by delivering primers one at a time directly into the Primer Plug and sleeve. This design eliminates the need to touch primers, reducing the risk of misfires caused by greasy or contaminated fingers. The nylon Primer Pick-Up system ensures primers stay securely in place while allowing for efficient reloading. With a tube capacity of 100 primers, this primer feed is compatible with Rock Chucker II Press, as well as JR and Reloader Special Presses.
