Starline 224 Valkyrie brass cases - In Stock!
Starline Brass prides itself on producing the highest quality brass case available. Their brass is comprised of 70% copper and 30% zinc and is vertically drawn during the manufacturing process which results in more uniform wall thickness. Cases are annealed between each draw to ensure consistent metallurgy in all lots. Each brass case is hand inspected to guarantee the highest quality possible.
Starline Brass is located in Sedalia, MO and has been in business for over 30 years. Trust Starline for your next reloads, you won't be disappointed. New, unprimed brass. This is not loaded ammunition. Bulk brass should be full-length sized, trimmed and chamfered before loading.
Preparation: Due to the manufacturing process and/or shipping, case mouths may not be perfectly round. To ensure a round case mouth, cases must be sized (or have the expander ball of the sizing die run through case neck) and deburred/Chamfered prior to loading.
Notes: 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.
Bison Armory Recommended Loads:
80 grain Sierra MatchKing: 28.4 grains of Winchester 760
80 grain Hornady ELD: 28.3 grains of Winchester 760
95 grain Sierra MatchKing: 26.9 grains of Winchester 760
All loads start with neck sizing the new brass (no lube required) and finish with a 2/3 turn crimp with the Lee Factory Crimp die. For the bullets listed I load them 2.280" to 2.285" COAL to fit PRI and ASC magazines.
Important: Winchester 760 (and ball powders in general) do not pack well into the case when poured in quickly. I recommend using a funnel and pouring the powder in slowly, about 2-3 seconds to charge a case. In this way the powder will seat as deeply as possible. A drop tube on your powder measure should also work.
As with all hand loading, start a grain or two low and work up. These loads are not particularly hot, but give supersonic performance well past 1000 yards and have shot very accurately for me from 100 to 300 yards.
