Sierra GameKing 7 mm/.284 Cal (.284) 150 gr. SBT Box 100
For rifles chambered in 7mm cartridges, this bullet has the heavy, double-tapered Sierra jacket for hunting. The 150 grain #1913 Spitzer Boat Tail bullet is a little heavier and thus provides a high ballistic coefficient compared to the 140 grain bullet. It is an excellent choice as a lighter bullet in any of the 7mm magnum cartridges for use at medium to long ranges. Both bullets are superbly accurate and provide excellent expansion with good penetration on medium game at ranges to 500 yards.
In handguns the 150 grain #1913 bullet is considered too “tough” for smaller cartridges, such as the 7mm TCU and 7mm BR. However, these bullets are seeing much use in the Remington XP-100 chambered for the 7mm-08 Remington or in similar cartridge/handgun combinations for both target shooting and hunting applications. This bullet is a good choices when driven at 2500 fps or more for medium or large game at typical handgun ranges. Using this bullet for hunting is limited to muzzle velocities achievable with only a select few cartridge and handgun combinations, but no such restrictions apply to target use. This bullet can be used in all 7mm cartridges for target shooting.
The #1913 was introduced in 1987.
