Grendel vs 308

[stanc]

There was a thread on another forum where the op asked which was the better round for an ar15 or if he should get an ar10 in 308. He wants a longer range hunting rifle, but wants to stick to an ar platform. Since I went through the exact same journey, I posted this. There was of course a storm of ignorance as always. My data shows even with a considerable handicap, the grendel performs really well...

308 is Rem 700 PSS
26" factory barrel
175 SMK 2674 fps hand loads

6.5 Grendel is a home build
20" Krieger barrel SAAMI 6.5 Grendel chamber with Maxim bolt
123 SST 2438 fps factory Hornady

It's too bad you didn't say that was your intent. By comparing a 26" barrel, .308 bolt-action with hand loads to a 20" barrel, 6.5 Grendel AR15 with factory ammo, it appeared to me that you were trying to make the Grendel look bad.
