The Sierra 4345 is a 145 grain 6.5mm (.264) Tipped GameKing (TGK), a polymer-tipped boat tail hunting bullet for the 6.5 Creedmoor, 6.5x55 and other 6.5mm cartridges. Introduced in 2024 and engineered around the 6.5 PRC, the 145 grain #4345 gives that cartridge a heavy tipped bullet with a G1 ballistic coefficient of .597 to make the most of its velocity.
The polymer tip initiates expansion and lifts the ballistic coefficient, while the heavily constructed jacket controls that expansion for deep penetration on medium and large game. The tip also protects the nose in the magazine and keeps the ballistic coefficient consistent from shot to shot, which shows up as tighter groups at longer range. Tipped GameKings feed cleanly through box magazines and suit both bolt actions and semi-automatic rifles.
