    Default 6.5 Grendel

    Isn't the 6.5 mm Grendel supposed to be based on the 6mm BR, which I read somewhere is based on the 7.62x39? Wonder if the AK could be converted to the Grendel. Ballistics are supposed to be very impressive.

    A-Yep! Do a quick site search for "Grendel" and you'll find the threads - there is an extremely LONG thread discussing the build issues, and some caliber conversion/wildcat discussions.

    The big issue is the fact that reamers are practically non-existant.

    NO! NO! the 6.5 grendal is based on the 6.5mm PPC with the neck moved forward
    the 6.5mmPPC is based on the 6mm PPC. the 6mm ppc is based on the 22 PPC. the 22 PPC is based on the 220 russian. the 22 russsian is based on the good ol 7.62x39. The 6.5 grendal shares the same rim as the 7.62x39 and can be formed from it as well.
    the bench rest series of rounds is derived from basicaly a cut down 308 with a smaller primer pocket. it uses the .470 rim and base same as the 308, 30-06 ect.
    ppc and benchrest rounds are designed for the same purpose Benchrest shooting but that is all they share.
    Like HC said scroll down there is a lot of discussion on 6.5 grendal, 6.8 spc. 6.5x39 ect

    Good call on that I didn't really pay attention to that part.

    The Grendel actually has more capacity than the PPC.

    looks to me like you could get a 6.5 barrel blank and a 6.5g reamer seems like i saw one the other day for $90 after a 60 day wait on the back-order.--

    you would have to turn the barrel down to AK form so it would be a pretty involved project.

    my guess is that you could use 5.56 mags from a galil or the new ak-223 mags.

    i don't really know if the 6.5 is going to take off though--tough to beat the old AK in 7.62 IMHO.

    6.5 has got its niche. As does the whisper. The nice thing about the Grendel is both the lack of recoil, a flatter path (flatter then the .308), and that you can use it in an AR upper, or in a bolt gun. I've even seen one in a Mini 30, after an old barrel was swapped out. Its on my list for buys this year.

    You can spend hours reading about the Grendel here.

    Again a note of caution every thing I have read up to about 6 monthes ago says that the reamers that are avaliable are set up for boltaction rifles. from what I have been able to gather guys using these reamers on AR,s have had trouble making them work. Alakander arms goes into alot of stuff claming that his specs are differant. (likely in the neck dia and free bore) this may have changed recently as I have been doing other projects. mags are said to be tricky as well. I saw today that copes has AR 6.5 mags for around $25 that likely could be modifed or an adapter could be bought. as far as the barrel that would be pretty straight forward.
    If something has changed and makers are offering a reamer suitable for an autoloader I am interested. do you have a link to your barrel source??? Also keep in mind the chamber pressure is higher than the 7.62x39 I dont think this is a beag deal but always must be considerd.
    Personaly every thing I can tell about this round is it seems to be better than the 6.8 SPC in almost every department except close range energy and that is only slightly. I have shelved my plans on it for now as I am working on a 260 (6.5mm) remington that will kick the grendals ass and be cheaper to shoot IMOA

    It's only metal, it's not magic.

    what about necking down a 762x39 to 6.5? no its not a grendel , yes the case capacity is slightly lower, you would have to have a reamer modified, you could use a standard mag. I know it has been done as there are reloading specs out there.
