The Forster Full Length Sizing Die – 300 PRC offers maximum flexibility, thats why most reloaders start their collection of Bench Rest dies with full length sizers. The die sizes the case neck and body, sizes shoulder to set headspace (length), deprimes, and expands the case neck. Machined by hand with one-piece reamers. The exclusive elevated “E-Z” out expander ball system makes the difference in this sizing die.
