Home Forums Hunting & Shooting AR and Tactical Rifles 6.5 Grendel or 6.8 SPC for best all round AR caliber.

I also saw a chart somewhere, that at long range the 6.5 actually retained more energy than a 308. It is one of those calibers that does more than it should, like the 6mm PPC. The 6.5 Swede is also a good one. In Sweden, they use their 6.5 to hunt moose.
