Lapua to make 6.5 Creedmoor brass

  • I saw this post this morning and thought it was worthy of a share. Can someone help me understand the statement about small primers and smaller flashhole make for a more accurate round?!

    "Lapua's 6.5 Creedmoor is here!

    We are happy to announce the addition of the 6.5 Creedmoor case to the Lapua line! Despite a relatively short time on the marketplace, the 6.5 Creedmoor has made a tremendous splash in the field, rapidly becoming one of the most requested cases we hear about from shooters.

    Lapua's 6.5 Creedmoor is designed to function in a short action, which is also a plus for hunters, vitally concerned with the rifle’s weight and compactness. In fact, many of the same features which make for a successful competition cartridge, translate nicely to the hunting fields as well.

    For most species of mid-size game such as deer or boar, the Creedmoor will prove to be a deadly performer. And while the selection of high grade Match bullets in the 6.5 bore size is tremendous, there’s no shortage of exceptionally good hunting bullets either. The 6.5's as a group have always been known as excellent performers on game.

    Made with Lapua’s typical dedication to precision, our new 6.5 Creedmoor case has been refined just a bit, to make it an even better performer. We’ve opted for the small rifle primer, which normally produces an optimized ignition and better accuracy than large primers in mid-sized cartridges like the Creedmoor.

    We’ve also incorporated our smaller diameter flash hole (1.5mm, rather than the industry standard 2.0mm), which has proven to provide enhanced accuracy, and is used in a number of our other accuracy oriented cases. In this respect, the new 6.5 Creedmoor joins the ranks of our other dedicated accuracy cartridges such as the .220 Russian (6mm PPC), the 6mm BR Norma, the 6.5x47 Lapua and the .308 Win. Palma cases.

    And naturally, the new 6.5 Creedmoor will be made with our well known Passion for Precision. Strictest control over the metallurgy, the forming and drawing processes, precise annealing all performed under the watchful eyes of our production experts. For you, the handloader, that means the durability for which our cases are famous, combined with consistency and long life. Already proven in competition, we predict that the 6.5 Creedmoor will be a force to be reckoned with for many years to come.

    The 6.5 Creedmoor case by Lapua will be available in Q1 2017. "

  • Smaller amount of priming compound and smaller flash hole leads to more consistent ignition. That is their theory.

    Considering how ridiculous my 22 creedmoor shoots... I don't think it's as important as they think it is. Time will tell about their decision.

  • Screws over anyone with a R700 that doesn't have a PTG bolt or a bushes bolt.

    Probably a few other platforms as well, I remember AIs having pierced primer issues.

    Seemed like an unnecessary change to me.

    I don't completely agree with you on it screwing anyone with a R700 without bushed bolt. Although I do agree that the change to small primer wasn't necessary.

    How many hundreds of thousands of 223 Remington 700 actions are out there running without issue with proper ammo?

    I think the primary issue with small primers in 308BF cartridges - especially the x47 cases - is that guys are pushing them to excess pressures. How many reports to do you see of guys running 6.5x47s with 140s pushing them to 2800 fps and 6x47's with 115's at 3100? Throw a large rifle primer and standard pin at that same situation and I expect you'd see an equal number of pierced primer problems.

    I've shot almost 3000 rounds of BRX through a Defiance receiver with standard pin and never pierced a primer. Sure, I would see some cratering now and then on a hot day or long string of fire, but I've seen the same with large rifle primers and standard pins. Of course, I wasn't trying to push the cartridge beyond its means.

    Having a small firing pin and tight pin to bolt fit is NOT a free pass to run at higher pressures!

  • I thought of saying that guys will be running 6.5 creedmoor way faster now and not realize they're way over pressure.

    Also thanks I thought it was a clearance issue.
