The .240 Weatherby Magnum remains the world’s fastest commercially available 6mm. A powerful, fast-killing cartridge, the .240 is a belted .30-06 parent case necked down to 6mm (.243”) with a double radius improved shoulder.
A 100-percent copper bullet with a polymer tip to boost ballistic coefficient to improve long-range ballistics and provide fast expansion. The four razor sharp cutting petals double the bullet diameter that wreak extensive internal damage and produce massive wound channels. The TTSX is extremely accurate and has great expansion.

Hammer Bullets™ are turned on a CNC lathe and use a unique solid copper blend that is designed for maximum terminal performance. Each bullet is weighed and micrometer measured as it is produced. The result is an incredibly consistent product with unparalleled quality control. The hollow point design, initiates expansion upon impact, shedding petals immediately, with the remainder of the bullet staying intact with a blunt front for optimal wound channel. All Hammer Custom Bullets are designed to optimize Weatherby’s flat shooting cartridges.
Take a deeper dive into Hammer Bullets with our On Our Mark podcast. We sit down with Bryan and Steve of Hammer Bullets to talk about the performance and what makes Hammer bullets different from similar projectiles.

The InterLock® features an exposed lead tip for controlled expansion and hard-hitting terminal performance. A secant ogive design — one of the most ballistically efficient profiles ever developed. The raised ring inside the jacket is embedded in the bullet, combined with the one-piece core, keeps the core and jacket locked together during expansion to retain mass and energy.

I’ve always been fascinated with Weatherby cartridges. Looking at the ballistics of the 240 Weatherby I believed I had found the perfect all around deer cartridge. I couldn’t have been more right. The deer I have shot with the 240 looked like they were dropped by the hammer of Thor! Including a large bodied Montana 8 point at a measured distance of 305 yards. Also took a nice Bull elk on that trip at 210 yards with one well place shot. All with the 80grn TTSX. One very accurate bullet from my gun. Thank you Weatherby
Paul Smith –
Barnes TTSX 80 grain bullet. Purchase them right here on the Weatherby site. Solid copper bullet for the Prune Pickers in the west! They shoot well in my Mark V. Not cheap, but what is anymore :< (
Basil Mackrodt –
Love my 240 w.meg shot a lot of 280 pound boar drop them in their tracks. Problem is in California I cannot find non lead ammo for my rifle can someone suggest where I can buy them in San Jose. CA.
Thanks

I have been hunting with my 240weatherby since 1970 I have taken Sox 50 whitetail deer ag nd many antelope with it using 85 or 100g nosier handload
They are instant death to both out t350 yds I have a mark 5 deluxe
N8iV Warrior in Central Oregon –
My rifle loves the 100 gr spritzers and it lays the smack down on monster Mule deer bucks in Central Oregon. I have shot the factory round on steel out to 800 yds on steel and very consistent Ammo on steel. I will be purchasing more and recommend this Ammo to family and friends. Great job Weatherby keep up the good work and beautiful rifles in the Mark V series.

I’ve been hunting with my 240 mag for over 10 years. I’ve been shooting 100 grain spitzers and have seen great accuracy and haven’t had to chase down any whitetail. In fact it’s hard to find the bullet afterwards, it expands and explods very well, dropping deer in there tracks. Would recommend this caliber to anyone wanting performance without a lot of recoil.
Pistol Pete –
I bought a Vanguard Back Country in 240 Weatherby Mag last year. The rifle loves the 100 gr. Spitzers. Clover leafs 3 rounds at 100 yd. easily. Great Whitetail deer and black buck round.
Noel J –
I am a Weatherby product fan, with much fun and success in a few calibers. In a factory .240 Fibermark circa 1995, the 100 nosler partitions have higher velocity and are a going Jessie. On 175 lb Texas whitetail, this bullet is very, very potent with excellent accuracy and hits with a whallop out to 300 yards. Many deer instant lethal drops. Partitions are not suppose to be a long range bullet…nonsense. Recoil on this magnum load is very manageable,
Spitzers represent great value load.
On small to medium game, the .240 Weatherby is a smoke stack lightening bolt.

Terrific results with the 100 grain bullet 26 inch barrel 3 rifle in 30 years ,the farthest shot in the hungarian plain 400 meters + with Swarowsky 7×55 fix – no german caliber could equal the 240 w.mag,
A life time of succesfull roe Dear hunt thanks to your terrific modern caliber,and rifle –
Thank yoy Roy
