Ah yes that's one of my links in my "reamer" favorites folder!Originally Posted by Lt762x39
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:
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.
$270- 500 Rounds SOFT POINT. Ouch...
