Alternative to 6.5 Grendel?

[SHORT-N-SASSY]

Of course not. But if I'm going to travel all that way to shoot Variable's 5.56 Shrike, I figure I might as well make the trip really worthwhile, and see about doing some major blasting with one of his 6.5 Grendel carbines.

Prompted in large part by your tentative travel plans, I moments ago called WOLF Performance Ammo. To update: They expect to be in receipt of 6.5 Grendel Steel Case ammo, next month/2nd quarter, 2014; Distributors (MidwayUSA.com, etc.) will have it in stock, 3rd quarter, 2014. Re the question, Berdan or Boxer primers? Boxer primed!
