RCBS Small Base Sizer Die .223 Rem

Semi-automatic rifles such as AR-type rifles can be fussy about case dimensions. A small base die sizes the lower body of the case slightly further than a standard die for reliable chambering. RCBS has been making reloading equipment in Oroville, California for decades and is one of the best-known names in the hobby.

• Cartridge: .223 Remington
• Type: small base full-length sizer
• Fits any press with standard 7/8-14 die threads.

Keep your dies and tools clean and lightly oiled to prevent rust, and always follow published load data.

Set up dies according to the maker’s instructions, lubricate cases before full-length sizing (unless using carbide dies on straight-walled cases) and check your overall length often.
