The .338 Razorback is a wildcat rifle cartridge chambered for .338-caliber bullets, developed for hunting applications — particularly feral hog and large game. The name references the razorback hog.

History: The .338 Razorback emerged from the wildcat tradition of necking existing cases to .338-caliber. The .338 bore attracts wildcatters for its combination of high sectional density and manageable recoil relative to delivered energy. The Razorback variant was developed for the feral hog hunting market that expanded significantly in the 2000s across the southern United States.
