For rifles, when Remington standardized the popular .35 Whelen wildcat cartridge, Sierra designed the 225 grain #2850 Spitzer Boat Tail bullet for the 35 Whelen and similar cartridges. This bullet has a heavy, double-tapered jacket drawn to very tight tolerances and a special alloy core for deep penetration and good expansion on heavy game. It also has the classic Sierra SBT shape for exceptional ballistic efficiency among 35 caliber bullets. This bullet delivers incredible accuracy and retains velocity and energy exceptionally well downrange. The flat trajectory extends the useful range of all appropriate 35 caliber cartridges and delivers smashing power even at long range. Although not suited for the 35 Remington cartridge, it is well matched to the more potent 358 Winchester and 350 Remington Magnum cartridges, as well as the 35 Whelen. In any of these cartridges, it is appropriate for all North American big game.
In handguns, while the 225 grain #2850 Spitzer Boat Tail GameKing bullet is not recommended for hunting due to its extreme toughness, it is still useful to the handgunner. Those hearty silhouette shooters who can't get away from a favorite 357 Herrett or 35 Remington have a streamlined, high ballistic coefficient, low crosswind sensitivity bullet to use at 200 meters. This bullet can be fired at 1700 fps from a T/C Contender with a 10 inch barrel in 357 Herrett or 35 Remington, and it won't leave a ram standing. Also, it is capable of half minute-of-angle accuracy.
