Weatherby Select Plus 257 Wby Mag 100gr Barnes TSX Lead-Free Ammo

The Weatherby Select Plus 257 Weatherby Magnum delivers exceptional long-range performance with Barnes Tipped TSX lead-free bullets engineered for maximum expansion and weight retention. This premium hunting ammunition combines Weatherby's legendary velocity with Barnes' proven copper construction for devastating terminal performance on medium to large game.

What Makes This Different

The Barnes Tipped TSX (Triple-Shock X) bullet features an all-copper construction that retains 99% of its original weight while expanding to nearly twice its diameter. Unlike traditional lead-core bullets that fragment and lose mass, the TSX design creates four razor-sharp petals that slice through tissue while the solid copper shank drives deep for complete penetration. The polymer tip initiates rapid expansion at velocities as low as 1,800 fps while maintaining structural integrity at magnum velocities exceeding 3,400 fps.

Field testing demonstrates consistent sub-MOA accuracy in quality rifles with proper bedding and scope mounting. The 257 Weatherby Magnum's flat trajectory makes it exceptionally effective for open-country hunting where long shots are common. The Barnes TSX bullet performs reliably on game ranging from antelope to elk, creating massive wound channels while maintaining straight-line penetration through heavy bone and muscle.
