The .240 Weatherby Magnum has always been about velocity. When Roy Weatherby developed this cartridge in 1968, he was thinking about one thing: pushing a 6mm bullet faster than anything else on the market. That legacy lives on with Select Plus ammunition, which pairs Weatherby's magnum design with Barnes' proven bullet technology. You're looking at about 3,500 fps from the muzzle with an 80-grain projectile—one of the fastest commercial 6mm loads you can buy. That velocity translates directly into a flatter trajectory and less wind drift at distance, which matters when you're taking chances beyond 200 yards.
The Barnes TTSX is a solid copper bullet with a polymer tip and hollow point design. When it hits, the polymer tip compresses into the hollow cavity, forcing the nose to peel back into four distinct cutting petals. That's where the expansion happens—fast, controlled, and with excellent weight retention. The solid copper construction means these bullets hold together through tough shots while still delivering the energy transfer you need for clean, quick kills. Lead-free ammunition also opens doors if you hunt areas with restrictions or prefer avoiding lead altogether.
With an 80-grain TTSX and a muzzle velocity around 3,500 fps, you're working with a ballistic coefficient of .333. That means better velocity retention and less bullet drop compared to heavier loads. At 300 yards, you're still carrying plenty of energy to take medium game responsibly. The cartridge itself was designed for medium game out to extended ranges, and this ammunition takes full advantage of that. Reloadable brass means once you work up a load that shoots well in your rifle, you can keep running the cartridge for years.
Yes, the Barnes TTSX bullets are designed to perform reliably in both modern and older .240 Weatherby Magnum rifles. The ammunition is loaded to standard factory pressures and will function safely in any properly maintained .240 Weatherby rifle, whether it's a Mark V, Vanguard, or other platform.
The 80-grain TTSX generates more velocity than heavier loads, which translates to a flatter trajectory and better wind resistance at distance. However, heavier bullets (like 100-grain loads) retain more energy farther out. The 80-grain is excellent for ranges to about 300 yards on medium game, while 100-grain options offer better performance at extreme range if your rifle prefers them.
Absolutely. The brass cases are reloadable, which means once you shoot a box, you can resize, reprime, and reload them with new bullets and powder. This makes the cartridge much more economical long-term, though you'll need reloading equipment and dies for the .240 Weatherby Magnum.
Barnes TTSX bullets are all-copper, lead-free projectiles with a polymer tip and hollow-point design. On impact, the tip drives backward and forces the bullet to expand into four sharp petals while retaining nearly all its weight. This combination creates a large wound channel while maintaining penetration—ideal for ethical, quick kills on medium game.
