Unprimed Brass Cases

9x23 Comp Brass (Small Rifle or Small Pistol primer)

9 Super Comp, 9x23 Win, 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 change will in no way affect performance of case for use with lighter bullets.

*Starline Brass does not sell any loaded ammunition. What you are purchasing are brass cases only and will need to be loaded into ammunition in order to be fired from a firearm.

I find that Starline Brass is one of the modern companies with an old world ethic approach in adding their customers. I have purchased numerous items and have found each and everyone of excellent quality. In addition the staff I have communicated with were helpful as well knowledgeable, As always their assistance is greatly appreciated. I use and would suggest anyone of their products to anyone serious about handloading.
