This two-die set is intended for reloading bottleneck cases, and consists of a Full-Length Sizer Die with an Expander-Decapping Unit, and a Seater Die with Bullet Seater Plug. Standard 7/8-inch-14 thread. Shell holders sold separately.
The Full-Length Sizer Die brings the case to SAAMI minimum cartridge dimensions. It sizes the outside of the case, de-primes and expands the neck to accept the bullet. The die has vents to prevent case damage caused by trapped air and for excessive lubricant. Headspace is held to minimum tolerances to avoid changing the case body length during full length sizing.
The included Seater Die with Bullet Seater Plug has a built-in roll crimper to secure the bullet at the same time as it's seated.
Sizing dies with tolerance twice as stringent as typical firearms and ammunition for consistent chambering round after round.
Fine body knurling for easy, non-slip adjustment.
Hardened die bodies.
Easy, adjustable expander-decapping unit locks in place, eliminating slippage.
Three-piece expander/decapping unit lets you replace the decapping pin in a snap.
