Darrik,
I was actually surprised when Tom listed the 7-08 as a possibility, since he's Mr. 7x57. But you never know when some, ah, older rifle loony might consider catching up to the modern world....
Im shooting a 6.8spc for Gods snake...it don't get no more modern than that!
But it is in a bolt gun.....Jim Zumbo told me not to warm up to the AR platform...that it was just a fad....
