Description
The Select Plus line delivers what serious rifle hunters have relied on for decades: magnum velocity paired with premium bullet construction. This particular load pushes the 100-grain Barnes TTSX at 3,570 feet per second, giving you the kind of flat trajectory that defines the .257 Weatherby Magnum experience. You get a modern, polymer-tipped all-copper bullet that combines the tracking accuracy of a solid projectile with the expansion characteristics hunters need.
The Barnes TTSX design works through controlled expansion. The polymer tip boosts ballistic coefficient for extended-range performance, while four razor-sharp cutting petals deploy on impact to double the bullet diameter. What matters in the field is that you get rapid, consistent expansion with nearly complete weight retention. That means deeper penetration and more predictable performance across a wider range of impact velocities than traditional jacketed bullets allow.
.257 Weatherby Magnum for Medium Game
This load sits in the sweet spot for deer, antelope, and similar-sized game. The 100-grain weight carries enough energy to deliver clean, reliable kills at extended distances without the overkill that comes with heavier magnum offerings. The .257 Weatherby itself is known for mild recoil relative to its velocity, which matters when you're spending the day in the field or setting up for precision shots. Multiple hunters report sub-MOA accuracy from quality rifles, and the consistency of factory ammunition like Select Plus makes that kind of performance repeatable.
Lead-Free Ammunition Loaded on Brass
This ammunition ships in reloadable brass with a boxer primer, so if you reload you've got usable component. The lead-free projectile satisfies requirements in areas where such rounds are required, without compromising the ballistic characteristics you need. New production, non-corrosive composition means reliability across a wide range of hunting conditions.

Frequently Asked Questions
What is the point-blank range for this .257 Weatherby Magnum load?
With proper rifle zeroing, the 100-grain TTSX has a point-blank range of approximately 350 yards, meaning minimal hold-over adjustments needed for game within that distance. This flat trajectory is one of the defining characteristics of the .257 Weatherby Magnum compared to other popular hunting cartridges in its class.
Is this ammunition suitable for elk hunting?
The 100-grain TTSX is marginal for elk at moderate to extended ranges due to the lighter bullet weight relative to elk-sized game. Many hunters prefer 110-grain or heavier loads for elk, though well-placed shots at closer ranges have proven effective. The .257 Weatherby excels on lighter big game like deer, antelope, and sheep where its flat trajectory and mild recoil are genuine advantages.
Why choose all-copper bullets like the TTSX?
All-copper designs shed weight less aggressively than traditional bonded-core bullets, which means deeper, more consistent penetration across varying impact velocities and tough materials. The TTSX also tracks more predictably through bone and muscle, making shot placement less critical compared to softer-expanding designs.
Can I reload the brass from this ammunition?
Yes. This ammunition uses reloadable brass cases with standard boxer primers, so once you fire it, the empty cases are suitable for handloading. The .257 Weatherby Magnum is popular among reloaders because the magnum case capacity and velocity potential make it rewarding to work with.
