Hornady SST vs Barnes TAC-TX | 6.5 Grendel Hunting Ammo Test & Ballistics Breakdown

In this video, we pit two of the most talked-about 6.5 Grendel hunting bullets head-to-head: the 123gr Hornady SST and the 115gr Barnes TAC-TX.

Andy from Grendel Hunter walks you through real-world testing to see how these loads actually perform — not just what the manufacturers promise. We run them through soaked foam blocks and a line of water jugs to test for penetration, expansion, energy transfer, and bullet weight retention.

Then we back it up with real hunting experiences and field results from whitetail deer to antelope. Whether you're considering which 6.5 Grendel ammo to use this season or you just like watching bullets get put to the test, this video is for you.

Stick around to the end for ballistics graphs showing velocity, energy, and trajectory comparisons between both loads — and see which one might work best for your setup.

💥 Real tests. Real results. From hunters who use this gear in the field.
