60 Something Mag Better May 2026

The .60 caliber has its roots in the early 20th century, when the United States military began experimenting with larger caliber rifles to improve the effectiveness of their sniper rifles and anti-materiel rifles. The .60-06 Springfield, also known as the .60 caliber, was developed in the 1950s as a potential replacement for the .50 BMG (12.7x99mm) cartridge. Although it never gained widespread adoption, the .60 caliber has remained popular among niche users, including hunters and long-range shooters.
