Description

The 7mm Weatherby Magnum has a real advantage for hunters who want magnum performance without handloading. This cartridge was designed in the early 1940s and gives you velocity and trajectory that puts it ahead of more popular alternatives. The Weatherby Select Plus loading with 140-grain Barnes TTSX delivers that speed reliably, shot after shot.

What Makes the Barnes TTSX Projectile Stand Out

Barnes bullets are built from solid copper with no lead, which means they retain nearly all their weight when they expand. The polymer tip improves the ballistic coefficient for flatter shooting at distance, while the four cutting petals create substantial wound channels through bone and tissue. That weight retention matters because the bullet doesn't shed fragments like traditional lead cores do, so penetration stays deep even at velocity loss downrange.

Performance From the 7mm Weatherby Magnum

This ammunition launches the 140-grain TTSX at 3250 fps from a 26-inch barrel, generating 3283 foot-pounds of energy at the muzzle. That's plenty of power for elk, moose, and other large game at extended range. The flat trajectory from that velocity means you're not fighting massive bullet drop on open country hunts. Brass cases come boxer-primed and reloadable, so you can reload if you handload down the road.

Built for Real-World Hunting

Weatherby Select Plus ammunition uses quality components including Norma brass to match the precision you'd get from your own carefully worked handloads. This ammunition works well for anyone with a 7mm Weatherby Magnum rifle who wants to hunt without the time investment of developing loads at the reloading bench.

Frequently Asked Questions

Can I reload the brass from this 7mm Weatherby Magnum ammunition?

Yes. The cases are made of Norma brass and are boxer-primed, so they're designed to be reloaded. This is a nice benefit for handloaders since 7mm Weatherby Magnum brass can be harder to find than some other calibers.

What kind of game is the 140-grain Barnes TTSX suitable for?

This load works well for elk, moose, and other large game. The 140-grain weight is on the lighter side for the 7mm Weatherby Magnum, which is why many hunters view it as ideal for medium to large game rather than as an overkill for smaller animals. The copper construction means it retains weight and penetrates deep.

How does the 7mm Weatherby Magnum compare to the 7mm Remington Magnum?

The 7mm Weatherby was introduced about 18 years earlier and delivers a slight ballistic edge due to its case design that maximizes powder capacity. While the 7mm Remington Magnum is more widely available and popular, the Weatherby version gives comparable performance and is an excellent hunting cartridge in its own right.

What is the ballistic coefficient of this ammunition?

The 140-grain Barnes TTSX has a ballistic coefficient of 0.394. The polymer tip helps boost the aerodynamics, which supports a flatter trajectory and better energy retention at distance compared to solid copper bullets without a tip.
