Lapua Lock Base Projectiles

The Lapua Lock Base Projectiles are legendary full metal jacket match bullets developed for shooters who demand exceptional accuracy, consistency and long-range performance. Originally designed by Lapua for military and competition applications, the Lock Base has earned a reputation as one of the most accurate FMJ projectiles ever produced and has seen service in military sniper ammunition as well as precision target shooting disciplines worldwide.

The Lock Base combines a Full Metal Jacket Boat Tail (FMJBT) design with Lapua's patented Lock Base technology, which was specifically developed to improve accuracy and maintain stability at higher velocities and pressures. Unlike conventional FMJ bullets, the Lock Base features a unique tapered rear section that enhances ballistic performance while maintaining excellent consistency from shot to shot.

Designed for mid-range and long-range shooting, the Lock Base offers outstanding ballistic performance, reduced wind drift and exceptional stability. Lapua's meticulous manufacturing processes ensure extremely tight tolerances for weight, jacket concentricity and dimensional consistency, helping precision shooters achieve repeatable results at extended distances.

The Lock Base projectile played a significant role in the development of the legendary .338 Lapua Magnum, with the 250gr Lock Base becoming one of the most respected long-range projectiles in military and civilian shooting circles.
