The RCBS 20415 Carbine 3-Die Set delivers precision reloading capabilities specifically engineered for .380 ACP cartridges. This Group B die set provides reloaders with the essential tools needed to produce consistent, accurate ammunition while extending brass case life through proper resizing and bullet seating.

What Makes This Different

RCBS Carbide dies eliminate the need for case lubrication during resizing operations, streamlining the reloading process while preventing stuck cases. The three-die configuration includes a full-length resizing die with carbide ring, expanding die, and bullet seating die with built-in roll crimp. This combination ensures proper case preparation and consistent bullet seating depth compared to standard steel dies that require lubrication.

Key Features

• Carbide resizing die eliminates need for case lubrication
• Full-length resizing ensures reliable chambering in all .380 ACP firearms
• Expanding die provides consistent case mouth preparation
• Bullet seating die with integrated roll crimp for secure bullet retention
