The 6.5 Grendel is quite possibly one of the more deceiving little cartridges on the market. It can easily be dismissed as diminutive and ineffectual at first glance. But upon a second review one might see a geometric similarity with cartridges like the 6mm PPC and 6mm B.R. Also one may dismiss that its intended design was focused directly on AR/MSR function. Secondly that it achieves its level of performance in the smaller AR-15 sized rifle, not the larger AR-10. Much can be said about how easily it might be overlooked, and equally as much about what a great cartridge and platform it proven itself to be in the hands of anyone who uses it.

When we look at the comparative loads and place the 6.5 Grendel in proper context, we might be rather surprised at the ballistic capabilities of the Grendel. Whether you are comparing it against the proven varminting capabilities of the 223 Remington or the deer slaying pedigree of the 6.5 Carcano & 7-30 waters, the 6.5 Grendel is quite impressive and I admit, possibly a little exciting. I look forward to your comments.
Good Hunting & Be Safe!
