RCBS Neck Expander Plug .264 cal

The RCBS Neck Expander Plug .264 cal is a precision reloading component designed for shooters and handloaders who prioritize consistency in ammunition production. This replacement expander plug is specifically engineered to integrate with the RCBS Neck Expander Die system, allowing for the precise expansion of brass case necks to exact specifications.

The expander plug functions by widening the inside of fired case necks after sizing, ensuring the correct dimensions for bullet insertion while minimizing friction and gaps. This critical step helps prevent case cracking, reduces runout, and promotes repeatable bullet alignment, which are essential factors in precision reloading. Manufactured by RCBS to stringent tolerances, the .264 specification is tailored for popular cartridges like the .264 Winchester Magnum and .264 Creedmoor.

Reloaders focused on producing match-grade rifle rounds or volume-loading hunting ammunition will find this plug invaluable. Its compact design (2.9 x 0.8 x 4.3 inches) fits seamlessly into a standard reloading press setup, making it a practical choice for those expanding their reloading operations. This plug is best suited for use with RCBS Neck Expander Dies specifically designed for .264 caliber applications.
