Your choice of 5.56 for an Armalite 180?
The Hi-Lo is: LakeCity-BrownBear. I have DRT’d large game with both.
from my personal page:
“Lessons of Vietnam: If the Almight had expected us to depend on the 5.56, He would have made all our enemies 2 feet tall”
:)
Seriously, virtually anything for practice, ONLY the Federal 5.56x45mm Nosler Partition for serious defensive work.
