    Ah yes that's one of my links in my "reamer" favorites folder!

    I think this would be good for a fire forming barrel or die, and as a roughing reamer on a semi barrel.

    I was reading the Clymer wildcat reamer design page and they suggest tolerances up UP TO .008" at the neck is acceptable for a semi. I'll guess an AK is about at that, and an AR is probably less. Most are around .003" from what I've read:

    http://www.clymertool.com/wildcat/index.html

    I agree that a reamer rental would be better for this caliber, and depending on the gas port the "match" chamber reamer may be good enough. An AK conversion would probably be OK for it. The original goal of the AK conversion thread that PT started was to make a long-range "target" rifle based on the 6.5 bullet. The Grendel is convenient way to do that, but not the ONLY way. I've already read that a 6.5 PPC cartridge exists, but I can't find specs on it yet. It seems like a no-brainer to build a reamer based on the 6mm PPC and neck-up to 6.5. I think the Grendel people made it just longer than PPC size so you can't swap the two around. I think... based on threads I've read.

    At this point, I doubt I'll build a 6.5 Grendel because there isn't enough reloading data and affordable reloading components to build one. And where's the affordable ammo?!?!? I'd rather build a 6mm PPC AK.

    A little work in PSP and viola! Note the grendel is on the right, PPC on the left.



    Grendel shoulder is DEFINITELY higher, meaning more powder capacity. Couldn't say how much... I guess I'd have to read up on the cartridges to know that.

    Shoulder base for 6.5 Grendel: 1.1456 @ Diameter: .4323
    Shoulder base for 6mm PPC: 1.0748 @ Diameter: .4299

    Shoulder base for 7.62x39 (parent for BOTH cartridges): 1.201 @ Diameter: .394

    yep they needed a little more case capacity to get that velocity up for the grendal.
    I m not knocking the grendal in any way just pointing out that one of the advantages of the AK is the abiliity to make it work with longer mags. If I had to be stuck with a AR15 then the grendal would be on my want list. I think the grendal necked back down to .22 or even .20 would make a fantastic varmit round with its extra capacity it would almost be in the 22-250 class.

    heres a thought order a custom .22 grendal reamer with a removable pilot (no propiarity rights) use it for a 22. grendal then also use it on a 6.5mm barrel with a differant piolet and then ream the neck area with the correct neck 6.5mm neck reamer. Neck reamers are realitvly cheap. on the issue of math chambers versus SA chambers. I know that when I orderd my 17-223 reamer it was .002 larger than the math tight version. apparently they had already designed one for guys building AR15,s in 17-223.
