7 mm/.284 Caliber (.284) 175 gr. SBT
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.
In handguns, the 175 grain #1940 bullet is recommended for hunting only in cartridges like the 7mm-08 Remington in the Remington XP-100 single-shot handgun, which can push this bullet at a muzzle velocity of 2300 fps. This bullet is also a fine choice for handgun silhouettes and long-range target shooting, where superb accuracy, high momentum and low sensitivity to crosswinds are required downrange. These bullets can be used in all 7mm cartridges for silhouettes and target shooting, although they may be too heavy for the cartridges of smaller powder capacity.

|I used Sierra's accuracy load of 61.1 grains of RL22 combined with the 175 grain Sierra SBT in my 7mm Rem Mag to shoot a lot of 1/2" to 3/4" groups. In my rifle, this load chronographs out to 2,900 fps.|
