Rifle

In rifles, this 100 grain Spitzer bullet #1540 has a heavy, double-tapered jacket to ensure adequate penetration with reliable expansion on medium game. This bullet may be the correct choice for hunting large varmints as well as deer or antelope. It also may be the bullet of choice in some rifle's because its flat base construction enhances accuracy in that particular rifle. In handguns, the 100 grain #1540 Spitzer bullet is too "hard" for use on field game due to the moderate velocities from all but the largest wildcat cartridges. However, this bullet will deliver to outstanding accuracy in long-range target competition and high momentum downrange for silhouette competition from handgun barrels with standard twist rates. The #1540 was introduced in 1956.

For rifles, this bullet is designed specifically for the 375 Winchester cartridge. It has Sierra's unique PowerJacket and provides outstanding terminal performance. Sierra's Power Jacket ensures positive but even expansion in conjunction with good penetration on medium to heavy game. The cannelure location is correct for crimping, and the flat point was designed for use in tubular magazines. This bullet is also very effective in the 375 H&H Magnum, but velocity should be kept around 2200 fps to avoid over-expansion in game. For handguns, although the bullet is designed for rifles chambered for the 375 Winchester cartridge, it quickly found a home in the 375 Super Magnum revolver. Thompson Center currently chambers the T/C Contender for the 375 Winchester as well. Designed for the modest velocities generated by 375 Winchester rifles, this bullet performs very well in a handgun. The large amount of exposed lead at the tip and the PowerJacket skiving assure quick, even expansion at all suggested velocities and ranges, making this bullet the best choice in this caliber for field use on game. Traditional Sierra accuracy assures success on medium to large game and silhouettes. The #2900 was introduced in 1987.
