#4052 - 458 SOCOM Brass (Large Pistol primer)

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.

When I first purchased brass from star-line I was originally skeptical of their brass/company; however, I have used it in everything from 9mm pistols to my 45-70 with no complaints, so I was confident the 458 SOCOM brass I needed would be of the highest quality. Shipping was fast and everything looked great upon arrival. I am willing to recommend Star-Line brass to anyone who reloads and needs brass. Do not hesitate to purchase star-line if you need brass for reloading.

This is the only show in town for .458 socom brass, but as such it is the best brass I have worked with (in any calibre). I am glad they make it, as my Wilson .458 socom is a fantastic AR, an auto that replicates my 45-70. Thank you guys.

I load my 458 fairly warm with H110 Hodgdon behind 325 FTX bullets with excellent results. To date I have reloaded my Starline 458S brass 11 times and no signs of thinning Web or other signs of fatigue. The price is unbeatable when loading compared to buying, load at your own risk.

since Indiana made the 458 socom legal to hunt with I have loaded a couple different brands of cases in this caliber the starline is very durable as some have been loaded 6+ times with minimal stretch and little wear. I highly recommend this product.

I bought a box of 500 and not a bad one in the box. I use them with Barnes TAC-TX, Lil Gun powder, and Remington primers. So far I've reloaded each one at least once. When they become available again I will get at least 500 more, maybe 1000. If you need them don't hesitate.

An update..,Been shooting a lot. This brass is giving me absolute, total satisfaction. Am very pleased with the quality!!!

This is the only brass that has ever been in my RRA. It seems to be very durable compared to brass I use for other calibers. I would give it 5 stars if Starline could build it faster. Such a long wait for my first order I was about to give up, and that was beforenthings got really crazy.

i use this brass in a rock river rifle. all the printed data i have seen is very hot! suggest you start at min. load. i experienced a few hurt cases from ex. pressures. i am happy / starline.
