The Hornady Critical Defense .308 Winchester 155 Grain FTX (80920) was engineered for shooters who demand trusted defensive performance from their rifle ammunition. Designed around the proven Flex Tip eXpanding (FTX) bullet, this load provides controlled expansion and consistent performance, whether used for home defense, patrol, or personal protection.
Hornady’s patented Flex Tip eliminates clogging through barriers, allowing the bullet to expand even after passing through heavy clothing or intermediate materials. Each round is carefully loaded with premium powder charges, uniform brass cases, and non-corrosive primers to ensure flawless function and accuracy.
While purpose-built for defense, this .308 load maintains the precision and reliability Hornady is known for — performing exceptionally well in both bolt-action and semi-automatic rifles. It’s a powerful and balanced option for those who rely on the .308 Winchester platform for home or ranch protection.
