If this forum post is correct, the 6.5 Grendel is about to be mainstreamed:
Well, today Alexander Arms announced a few things at the Big 3 writers event.
1. The Grendel has been accepted by SAAMI
2. They have released their trademark on the 6.5mm Grendel
3. They showed off steel cased Grendel produced by Wolf
4. They hired a very well respected gentleman named Wayne Holt to handle PR.
So, now ANYONE can make a 6.5mm Grendel. The steel cased ammo is being produced by Barnaul for Wolf Performance ARMS and Ammunition. Note Wolf now has a firearms division and is working with Izhmash and Molot. They are looking into Vepr and Saiga rifles in 6.5mm Grendel. Currently testing is being done on the Wolf steel cases to verify they are good to go. Wolf is claiming production ammo for 1st quarter of this coming year. They said now that they switched this from Tula to Barnaul things are progressing nicely. I think its very positive as Barnaul’s quality is well known for being a notch above Tulas. The steel cases look sexy….
Bob Reynolds at Templar Custom turned me on to the 6.5 Grendel and is currently in the process building me an SPR-style AR-15 with 18″ barrel. While I’ve always been thrilled with the performance of the cartridge, I didn’t like the bite in the wallet shooting it entailed. Market forces should create more variations in loading and potentially drop the price. I’m not sure I’m ready to shoot steel-cased ammo in something as pricey as a custom rifle, but it is nice to know I’ve got options coming in the future.
