10mm Auto Brass New Unprimed Starline Bag of 100

Starline 10mm brass. Starline strives to hold the closest production tolerances possible on every piece of brass they manufacture. All brass is produced within SAAMI specifications and includes a special heat treat process to enhance the strength and longevity of the brass case. This is new, unprimed brass. This is not loaded ammunition. All bulk brass should be full-length sized, trimmed and chamfered before loading. 100 per bag

Note: A light "staining" may be found on the case neck of new brass. This is due to annealing. Annealing is a process, performed by the manufacturer, which involves rapid heating to a specified temperature followed by rapid cooling. This process imparts cases with the proper hardness to securely hold a bullet as well as gives flexibility to expand and contract upon firing and repeated forming. The "staining" is a residue from this process. This stain may be removed by tumbling before loading.
