Based on published specs and my personal preferences, I've always wanted to get a Grendel. I like shooting things far away. I like precision. But you know, things have changed. The original 6.8 SPC chamber and pressures and rifling twist, etc, etc, was all messed up by Remington. Now the world has moved on. A new chamber (SPC II + others) and slower twists with fewer grooves has resulted in some amazing specs. I can't see how the Grendel has much left to brag about. And it is STILL hard to actually buy Grendel uppers and Grendel ammo. This proprietary stuff gets old after a while.
So I recently had a smith build me a 6.8 White Oak upper for my AR. I still don't have it in hand but I'm looking forward to it. I've bought some factory ammo plus brass and bullets so I'm very much looking forward to loading for it. And I've been reading a lot.

I'm especially interested in some of the results people have been getting with the Barne's TSX bullets. A 16" barrel sending one of those all copper bullets downrange at WELL over 3000 fps should kill deer out to extended ranges. (Some are getting them up to 3200 fps out of a 16" barrel.)

Place to buy proper factory loads and the right kind of brass. Small primer pockets!
