The Sierra 6mm (.243) 85-grain Varminter bullet is a spitzer-point design intended for high-velocity varmint and predator hunting, offering a flat trajectory and excellent accuracy. Built for rapid expansion, it delivers explosive terminal performance on small game while minimizing ricochet risk. This particular 85-grain version is typically a flat-base spitzer (SPT) rather than a boat-tail (SBT), despite occasional confusion in labeling. It performs well in cartridges such as the .243 Winchester and 6mm Remington, where it can achieve high velocities and consistent accuracy, especially with suitable powders and standard twist rates. While highly effective for pest control and small-bodied animals, its lighter construction makes it less suitable for larger game due to limited penetration.
