Starline Unprimed Brass Cases - 9MM SUPERCOMP (9X23) - 100 Pack

A.K.A 9 Super Comp, 9x23 Winchester, 9mm Super Comp 0.894 - 0.899 O.A.L. The 9mm Super Comp (9x23) is of a new design with a new head stamp as of 7-7-03. We have changed the head stamp to read 9x23 Comp to allow easier identification because it looked too similar to the .38 Super Comp head stamp. At the same time, we slightly changed the interior design to allow the seating of heavier bullets (i.e. 147 grains) but this change will in no way affect performance of case for use with lighter bullets. Starline prides itself on producing the highest quality brass case available. With a production process focused on quality not quantity, Starline makes the finest brass and has done for more than 30 years.
