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.
Originally named the .30-30 AR, the 300 HAM’R was developed by Bill Wilson in 2018 in his search for improved terminal performance in the AR-15 platform while still utilizing the standard 5.56 bolt carrier group. The 300 HAM’R has a substantial velocity and energy advantage over calibers such as the .300 Blackout and 7.63×39 which gives it .30-30 performance out of the AR-15. Bullets in the 110-150 grain range are optimal for the 300 HAM’R and deliver excellent accuracy. With proper bullet selection you have a firearm with excellent terminal performance in a low recoiling package that hits well above its weight class. This cartridge has been used extensively for hog and deer hunting and has even been used in Africa for plains game. Hodgdon CFE BLK powder gives excellent velocity and low pressures in this cartridge.
Brass Preparation: With bulk rifle brass you may sometimes notice a few case mouths are “out of round” or slightly dented below the shoulder. These imperfections occur in the final tumbling wash operation after the case mouth has been annealed. Brass manufacturers are aware of the case cosmetics and have worked to mitigate it, but due to equipment design, denting may still occur. Minor dents are normally removed in the first firing and will not affect case life or performance. On non-plated brass, you may also notice all the anneal stain might not be polished off, which may give the case neck a pinkish color. With some smaller caliber cases you may notice the case mouths to be slightly belled.
With all new rifle brass, you should first straighten out the case and case mouth, then chamfer and debur the case mouth inside and out. To straighten the case mouth, run the case part way into the sizer die and let the expander ball straighten the brass. To prevent the case neck from stretching, be sure to lubricate the case neck inside the case mouth.
If you are using Nickel plated brass, special care must be taken to lubricate the cases prior to sizing them. Nickel plating is harder than brass and the cases require more effort in sizing. In the event a case becomes stuck, purchase a stuck case remover; don’t use pliers, screwdrivers or other common household tools which could damage your sizing die.
