Weatherby Select Plus 338 RPM 185 Grain Barnes TTSX Lead-Free Polymer Tip Ammo - 20 Rounds

The Weatherby Select Plus 338 RPM with 185-grain Barnes TTSX ammunition brings modern ballistics engineering to backcountry big-game hunting. Weatherby's 338 RPM cartridge—introduced in 2022—was purpose-built to pair magnum power with the lightweight Mark V 6 Lug action, giving hunters a rifle capable of reaching distant game without the weight penalty typically associated with large-caliber magnums. This factory load delivers Barnes' proven all-copper TTSX projectile in a lead-free, polymer-tipped configuration, making it a choice for hunters in regions with restrictions on traditional ammunition.

The 338 RPM case itself is engineered for velocity. Developed by necking up Weatherby's 6.5 RPM design to accept .338-caliber bullets, the cartridge features a large body diameter, minimal body taper, and a 35-degree shoulder that maximize powder capacity. That case geometry translates to higher velocities from a magnum platform scaled to fit a practical, packable rifle—ideal for the hunter who covers distance to reach elk, moose, or other North American big game in steep or remote terrain.

Each box contains 20 rounds of Select Plus ammunition, Weatherby's premium factory load line. The 185-grain Barnes TTSX bullet is designed for controlled expansion and deep penetration, combining stopping power with the ballistic consistency you'll want for ethical, effective hunting shots at range.
