The 100-percent safesolution is, of course, to useonly the ammo of the calibertha1's stamped on the , Hornady states that itsnew .300 \X/hisper am mo isfully compatible with rifles, so this solvesthe problem, test rifle this month isa brand new Hunter AR fromLoki Weapons Systems, and itproved to be areal shooter.

I'm not sure about thetechnicalities of this, but Icantell you that it shoots great anddoesn't pick up foul-ing, even after manyrounds.

Aillived up to theirreputations for pinpoint accuracy. TheHornady I80-grain SST was very ac-curate in severalloads, and one is shownprimarily for reference. Velocity is quitea bit below the minimum 2,400 fps listedin the Hornady "Bullet Guide" in theirmanual, so expansion would probably benonexistent. No subsonic loads are listed,as these are primarily for suppressedritles, and data for such are found in vari-ous contemporary 's nice to see something "old" become"new," and the .300 BLACKOUT certainly isone of these. Nevertheless, in whateverguise you find it, it's miserly with powder,relatively quiet and highly ace urate.
