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.
