Product DescriptionThe RCBS Standard 2-Die Set is designed for reloading bottleneck cartridge cases and includes the essential dies needed for consistent sizing and bullet seating. The Full-Length Sizer Die features an Expander-Decapping Unit to resize the case body, deprime spent primers, and expand the neck to accept a new bullet while bringing cases back to SAAMI minimum cartridge dimensions. Vents help prevent case damage caused by trapped air or excessive lubricant, and headspace is held to minimum tolerances to help avoid changing case body length during full-length sizing. The included Seater Die uses a Bullet Seater Plug and incorporates a built-in roll crimper to secure the bullet as it is seated.Product Highlights Two-die reloading set for bottleneck cases with full-length sizing and bullet seating Full-Length Sizer Die returns cases to SAAMI minimum cartridge dimensions for reliable chambering Expander-Decapping Unit de-primes and expands the neck to accept the bullet Die venting helps prevent case damage from trapped air and excess lubricant Seater Die with built-in roll crimp seats and crimps in one step Specs Brand: RCBS Manufacturer Part Number: 24001 UPC: 850070830638 Set Type: Standard 2-die set Intended Use: Reloading bottleneck cases Included Dies: Full-Length Sizer Die with Expander-Decapping Unit; Seater Die with Bullet Seater Plug Sizing Standard: SAAMI minimum cartridge dimensions (full-length sizing) Crimp Type: Built-in roll crimper (seater die) Die Features: Vents to reduce risk of case damage from trapped air/excess lubricant Disclaimer: We strive to provide accurate and up-to-date product descriptions, specifications, and images; however, errors or omissions may occasionally occur.
