#4052 - 458 SOCOM Brass

I use mixed range brass for high volume plinking and training. But for serious accuracy work, hunting, self-defense, and obscure cartridges, I've used Starline exclusively for years. The quality's the best in the industry, the selection and availability are unmatched, and their customer service is outstanding. I've emailed them with technical questions on a number of occasions and they've always gotten back to me quickly and with detailed answers. In one instances I was questioning case measurements and wondered if there was a problem with my sizing die or its setup. They offered to check using their optical comparator and custom gauges if I would mail them a few cases. A FYI about the .458 SOCOM brass. I dropped the first few rounds into my chamber checker and they wouldn't fully seat. After double checking my setup I went looking for a answer and came across their FAQ that says "The only Starline cases requiring full length sizing prior to loading are the .454 Casull, .458 SOCOM, and sometimes the .45 Colt (depending on the bullet diameter to be used)." Heed that warning!

Shipped fast, outstanding product. Can't recommend starline enough

I use a lot of Starline brass: some because it's the only brand available (458 SOCOM), and others just because I've been very pleased with the quality. All told, I have or have had Starline brass for 223 Remington, 308 Winchester, 458 SOCOM, 45-70 Gov't, 10mm Auto, 9mm Auto, and 45 Long Colt. Always pleased with the results.

I've been reloading for more than a couple years now. After the dust settled about the 458 SOCOM I put one together and thought I'd give Starline a try I've been using their .308 and 5.56 brass for more than a couple years so I bought a bag of their brass at a gun show. Tested all of the brass in the bag and found it well within SAMI specs. Hats off Starline, you're QA is damn good. The first time through loading the brass it went better than I expected. The cartridge/cases were concentric and were easy to load. Fired them all at the range (over two days) and then reloaded. No issues with the brass being hard to work with. So, I've done this seven times. I started annealing the brass after the second round to keep it from work hardening. Most importantly, I have NOT had a single instance hardening or case breakdown. Very satisfied with another fine product from Starline. Thank you folks! Keep it up. V/R Al

This is the toughest, and best brass. I am a reloader with 50+ years of handgun, rifle, and shotshell experance, so when I started the 458 SOCOM, This was a step up from my 5.56. Starline you make an old reloader proud. I would not, think of buying anything else.

All I can say is WOW! From start to finish,THIS product is what Ive been looking. Outstanding brass! THANKS for quality you can count on Starline!!!

Outstanding product Exactly as it should be! Never disappointed in Starline

Great product, exactly what I expected from Starline. Can't go wrong with this company's products. Always top flight, never disappoints in quality and customer service is second to none. Service AFTER the sale. Outstanding!

Excellent Brass. Shipping was fast. After checking several dozen pieces out of the box all measured 1.575. First 10 test loads with 325ftx over acc1680 5 shot groupings all holes touching. Second group the same. This is with a Tromix barrel. Very impressed with Starline. All I need know is starline to produce 300 AAC Blackout brass! :-)

I have been reloading for over 23 years and used my own used brass or new brand name brass. I was apprehensive about using Star Line until after trying their products. Now I cannot say enough good things about their brass. They have good quality control procedures in place and provide a superior product for reloading. I have been using both their brass and nickel plated brass in a variety of calibers from 380, 9mm, 357 SIG to 45 LC, 45-70, 458 SOCOM and about half a dozen I did not mention for about two years now, so I had no concerns when I found out they were my only option for 458 SOCOM Brass. I am very pleased. Their 458 SOCOM brass and nickel plated brass slip right into my headspace gauge without re-sizing. The brass lasts beyond my expectation without annealing. I am more concerned about the brass from the factory ammo I ordered with the factory's headstamp on their brass, a noticeable quality difference from StarLine's. I strongly recommend StarLine Brass for all brass reloading needs.
