6.5 Grendel versus 6mm ARC for whitetail

[Konocti's Wigwam]

One thing I’ve noticed is that 120gr and higher class bullets from 6.5 Grendel hit the steel harder, or at least louder.

Interesting comment as I've seen a lot of folks using the 100gr in the Grendel. Not surprising that the larger projectile is louder, question is what will it do on game (for me, others may be more interested in accuracy).

IMO, it seems like a 1st world problem if a 6mm ARC is better than a 6.5 Grendel for whitetail. I keep trying to like cartridges that will fit in the mini action, but at the end of the day I seem to like a short action a heck of a lot better. Yet another 1st world problem is how many rifles do I need... The larger 6.5mm bullet seems to be a big advantage for game, where the 6mm bullet is most likely better for targets. 22 Creedmoor looks like some fun also...in regard to mini action.
