Sierra - Bullet - 25 (.257) 90 gr HPBT Gameking 100/Box

 GameKing Bullets: All bullets in this classification are for hunting and all have boat tails. Their shapes include hollow point boat tail (HPBT), spitzer boat tail (SBT), and full metal jacket boat tail (FMJBT). The bullets in this classification have medium to heavy weights in each caliber. With their boat tail shapes, they have high ballistic coefficients, retain their velocities well, and resist crosswinds and vertical winds well as they fly. These bullets are designed for a combination of penetration and expansion in medium and heavy game animals for their calibers. 

The 90 grain #1615 Hollow Point Boat Tail bullet was designed originally as a varmint bullet, but it has taken on an expanded role. This bullet is extremely accurate at all velocity levels, making it suitable for the entire range of 25 caliber cartridges. It will perform as a varmint bullet at high velocities, but it may also be used on medium game from smaller-capacity cartridges, such as the 250-3000 Savage and 257 Roberts.
