20rds – 257 Weatherby Magnum Weatherby 100gr. InterLock Ammo

20rds – 257 Weatherby Magnum Weatherby 100gr. InterLock Ammo Details

Who is better qualified to load 257 Weatherby Magnum hunting ammunition than Weatherby themself? This cartridge offers the outstanding accuracy and overwhelming terminal ballistics you need to take any North American game.

Weatherby loads cartridges of their own design, but they do not create bullets. They enlist an expert like Hornady for so important a job, which is why this round features the 100 grain InterLock. The Nebraskan bulletsmith’s legendarily concentric jacket combines with a balanced lead core and sleek jacket profile to give this round’s InterLock a 0.357 G1 ballistic coefficient. It holds a flat trajectory to reach 360 yards in a mere 0.35 seconds – at which distance the InterLock retains more than enough energy to humanely anchor an elk.

The InterLock’s jacket is both tapered and grooved to promote consistent terminal expansion even at very low velocities. As a soft point the bullet’s one-piece core ensures a wide and lethal wound cavity. The InterLock additionally features a cannelure and Hornady’s InterLock ring – both of which combat core/jacket separation so the InterLock can retain the weight and momentum it needs to penetrate deeply.

Weatherby makes certain an InterLock can exhibit its best performance by loading high-quality components according to exact tolerances. Truly all your rifle needs come hunting season!
