Starline Adds .338 Federal To Its Product Line – 6.5 Creedmoor, .300 Blackout And More To Follow Soon

If you are a reloader you know the name Starline brings quality to the table. To make things even better for the rifle reloader Starline adds .338 Federal brass to its ever-growing lineup of high-quality rifle brass.

In 2006, Federal and Sako worked together to bring the new .338 Federal cartridge into the marketplace. The .338  was introduced in 2006 by Federal and Sako. Those shooters looking for magnum level muzzle energies in a cartridge that provides less felt recoil might want to take a close look at the .338 Federal. Bonus for it fitting into an AR-10 magazine without reducing magazine capacity.

So sure, .338 Federal is exciting for some reloaders but the really exciting announcement hid in the ‘coming soon’ section of the press release. They will be rolling out 6.5 Creedmoor and .300 Blackout cases in the near future. This is of interest to me since I have a couple of .300 Blackout rifles as well as at least one 6.5 Creedmoor being built with another in the safe.

Adding yet another great source of quality brass to the list is a welcome addition for not only me, but likely many other reloaders. If you want to learn more visit Starline Brass on their website. MSRP for the new brass starts ar $145 for 250 cases.

    If they go with small rifle primers for 6.5CM, they will not be able to make the cases fast enough for demand.

      Agreed. I can’t wait to see what they roll out.

      Why small primers?

      • Tassiebush

        My understanding is it let’s the case handle higher pressure. from reading up on this round and 6.5x47lapua it has offered a significant benefit. The 6.5x47lapua case was designed that way and now it’s also being done for some creedmore cases giving it a boost.
        Edit: there’s also this from “The 6.5 Creedmoor was designed with a large rifle primer, but the Lapua 6.5 CM cases will feature both a small rifle primer and a smaller diameter flash hole. Lapua believes both of those things produce more consistent ignition, which means more consistent muzzle velocities … which is critical in the long-range game.”

        Case life in reloading is basically limited by primer pocket life especially if you are loading near max pressures. Primer pockets stretch open until primers literally fall back out. Cases also lengthen slightly with every firing and that’s why people trim them back. Brass flows. But once a primer pocket stretches there’s not an easy fix. Once it can’t hold a primer, the whole case is trash. Using a small primer pocket (and to a lesser degree a small flash hole) means there is simply a lot more material strengthening the case head and also a lot less primer acting on it.

        In a case like the 6.5CM there is not so much volume that a small rifle or small rifle magnum primer can’t ignite it all smoothly, as cartridges like the 6.5×47 demonstrate.

    WTF? Did the case heads give testimony against someone? What kind of marketing material pixelates the head stamp?

    • TechnoTriticale

      When the promotional collateral has to be done before final product is ready.

      But sure, any Photoshop hacker worth hiring should be able to ‘shop in credible headstamps (assuming the exact character sequences were known – some of the newer cartridge/calibers don’t have exactly obvious abbreviations, and SAAMI isn’t necessarily dispositive on that).

      Japanese gun porn.

      They were not head stamped the right caliber. At the time this was written a good quality photo was not available.

    • Hoplopfheil

      I was thinking it was some kind of image recognition that auto-detected a bunch of nipples in a row and had to blur them out.

    • Rick O’Shay

      I thought they were just trying to be funny and make a visual association between primer holes and brown holes.

    Good news. Starline makes excellent brass

    If that’s their price on 300 BO, they probably won’t be selling too awful much of it. That’s pretty pricey. Converted brass is well under $0.20 per piece. New brass starts around $0.50 (last I looked, I don’t use new), some higher.

    They make good brass, but it’ll be hard for them in the market for 300 BO. The others will do well though, I think anyway.

  • Old Vet

    Can’t wait for the .300, my old fingers are getting tired of converting .223’s.

    So $.58/round for .338 and once fired .308 brass is $.14/round. How hard is it to enlarge the case neck ?
