When Rifle Accuracy Surprises Even a UFC Fighter

When UFC veteran and backcountry hunter Chad Mendes picked up his brand-new AllTerra-X precision hunting rifle, he knew he was getting something special. What he didn’t expect was a scope kiss on his very first shot—a direct result of the rifle’s power paired with instant, dead-on accuracy.

That first shot at 490 yards? Center hit.

That kick to the face? A reminder— watch your form when settling in behind a 300 PRC for an uphill shot.
