This system ejects your cases for you, allowing you to leave your right hand on the press lever and your left hand dedicated to feeding bullets. It speeds up your single stage reloading significantly. Kit includes: Base plate, Ejection spring assembly, and discharge ramp. The case ejector system is designed for versatility and can be installed directly to your bench-top or installed on any InLine Fabrication Ultramount press riser. The adjustable ejector plate attaches via your right side press mounting bolt and stays compact to the press. This version fits the RCBS Rock Chucker Single Stage Press. The base plate also includes die storage for (3) reloading dies. (Only usable if your press is mounted on an Ultramount to provide the clearance underneath.) This system works perfectly with Inline's Quick change system.
