The 3-Die Roll Crimp Set is an essential toolkit for loading straight-wall cartridges with precision. This set includes a steel Sizer Die that sizes the case and de-primes it—note that cases must be lubricated before use. The Expander Die is designed to expand the case to the correct diameter for bullet insertion, while also imparting a case mouth flare/bell to assist in bullet feeding. Lastly, the Seater Die expertly seats the bullet and ensures a reliable roll crimp. RCBS, founded in 1943, has a long-standing tradition of excellence in the field of handloading ammunition.
