Starline Brass is made in the USA in Sedalia Missouri. The business is family owned. Starline has been making brass for over 4 decades.
Due to the packaging and shipping process, case necks are often slightly dinged or bent and need to be rounded up and sized to give proper neck tension. New and/or fired cases must be full-length resized or have the expander ball of the sizing die run through the case neck prior to loading.
