The Sierra GameKing 150 grain Full Metal Jacket Boat Tail (FMJBT) is a .30 caliber (.308) reloading bullet engineered for long-range performance and consistent flight. Its boat-tail profile reduces drag to help maintain velocity, flatten trajectory and reduce wind drift. This 150 gr FMJBT is offered in a 100-count box and is specified for use in semi-automatic rifles such as the M14/M1A and M1 Garand, and may also be used in handguns where a non-deforming bullet is desired to protect pelts at lower velocities.

Manufactured to Sierra’s GameKing standards, this 150 gr FMJBT provides consistent construction and ballistic performance for shooters who value precision and predictable behavior in both semi-automatic rifles and select handgun applications. The boat-tail design and jacketed construction make these bullets a practical choice for long-range practice, sighting-in, and short-range hunting where a non-expanding profile is preferred to protect pelts.
