Sierra - Bullet - 7mm (.284) 175 gr SBT 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. 

For rifles, this 175 grain #1940 Spitzer Boat Tail bullet is an excellent choice for most large game hunting applications. It has a heavy, double-tapered jacket and a special alloy core to ensure deep penetration and good expansion on the heaviest North American game and on heavy African plains game. It has the same basic ballistic shape as Sierra's famous 168 grain 7mm MatchKing bullet. Accuracy of this hunting bullet approaches that of the MatchKing, making this the best long-range big game bullet for any of the 7mm magnum cartridges. It is also used successfully in centerfire rifle silhouette matches.
