Sierra - Bullet - 7mm (.284) 160 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 160 grain #1925 Hollow Point Boat Tail is a true magnum bullet, being somewhat "tougher" than the #1920 for deeper penetration. Contrary to a usual assumption, this hollow point bullet is not particularly fragile. The nose opening is closed slightly to help retard initial upset, but even expansion is assured by four skives cut into the jacket. Of course, there is no exposed lead to be deformed in the magazine. The result is an excellent bullet for many big game applications.
