Drawing on our past and Roy’s vision of superior ballistic performance, Ed and Adam Weatherby continue to inspire the dreams of hunters and shooters around the world with the same innovation and pacesetting performance that has fueled this company for seven decades.
Initially a wildcat cartridge developed by Roy Weatherby in 1959 at the request of the United States Army. This white-hot cartridge is based on the 378 necked down to 30 caliber and packed with powder. Originally billed as the world’s fastest 30 caliber cartridge, it will push a 30 caliber bullet 3,500 feet per second. Reintroduced as a Weatherby production cartridge in 1996.
Have a MK V in 30-378 set up by Long Range Hunters in WY with a Huskama scope using the 165gr TXS.for my South Dakota 1000 yard rifle. Less than 1' groups at 200 yards and ground pounds everything. I've used it to take whitetail out to a half mile with zero misses and dropped in their tracks. Luckily I purchased five boxes of ammo with gun (when ammo was $15 cheaper) and still have 3+ boxes left after LRH used 14 rounds to set up rifle, 6 on deer and the rest for practice.
Where's the beef?

I have been trying to purchase Weatherby 30-378 130 grain TTSX ammo for months. Why is it so difficult to find? If it's not available at Weatherby.com, there's a problem.
