.338 Lapua Magnum

The .338 Lapua Magnum was the first cartridge and caliber to be developed specifically for military sniper applications. It was also a good bridge between 300 Winchester Magnum and 50 BMG.

STTU is currently involved in test and evaluation of a .338 Lapua Magnum built on a Stiller’s TAC338 action, Bartlein barrel, and McMillan A5 stock. Stiller’s Actions also won the USMC contract for the MK13 300 WinMag with their TAC300/MK13 action.
