Hard to beat the 6.8 for punch vs recoil vs size and normal hunting ranges. I’ve had 8yr olds killing stuff with them. I’ve used many of them…223, 6.5G, 300AAC, 357 Max is always the Legend’s daddy;), 7.62x39. I still have/use the 6.8 the most in small case hunting rigs. The Grendel is probably easier now, due to offerings and ammo availability, but I’d have kept one if it was in any way better or even as good….in my experience.
