Federal 300 WSM 200 Grain Features

Any hunt. Any range. Go beyond what you ever thought possible with Federal Premium Terminal Ascent. Bonded construction penetrates deep on close targets, while the patented Slipstream polymer tip initiates expansion at velocities 200 fps lower than comparable designs. The bullet’s long, sleek profile offers an extremely high ballistic coefficient, and its AccuChannel groove technology improves accuracy and minimizes drag. Available in a full selection of long-range hunting cartridges.

• Match-grade long-range accuracy in a bonded hunting bullet
• Extremely high ballistic coefficient
• Exclusive Slipstream polymer tip helps flatten trajectories and initiate low-velocity expansion
• Less wind drift and drop
• AccuChannel groove technology minimizes drag
• Copper shank and bonded lead core retain weight for deep penetration at any range

300 WS

The overall cartridge length is 72.6 mm. The cartridge case length is 53.34 mm. The bullet diameter is .308 in (7.82 mm), which is common to all U.S. .30 caliber cartridges. The principle at work in the short magnum cartridge is the fitting of larger volumes of powder in closer proximity to the primer’s flash hole, resulting in more-uniform ignition. .300 WSM has a case capacity of 80 grains of H2O. The .30-06 Springfield holds 69 grains of H2O; .308 Winchester holds 56 grains of H2O; 30-30 Winchester holds 45 grains of H2O. The .300 Winchester Magnum has a case capacity of 93.8 grains of H2O. While providing ballistic performance nearly identical to that of the .300 Winchester Magnum, 300 WSM does this with about 14 grains less powder. The .300 WSM also head-spaces off of the case shoulder, versus the older .300 Winchester Magnum’s belted head space design.

The advantage to this round is ballistic performance nearly identical to the .300 Winchester Magnum^[2] in a lighter rifle with a shorter action burning 8 – 10% less gunpowder. A disadvantage of cartridge case designs with relatively large case head diameters lies in relatively high bolt thrust levels exerted on the locking mechanism of the employed firearm. Also, in small ring actions the larger chamber diameter removes more steel from the barrel tenon, making it weaker radially.
