Details

By far the most popular and versatile Weatherby cartridge available. The 300 Weatherby Magnum had the flattest trajectory, longest range and the greatest killing power of any 300 magnum on the market until the 30-378 Weatherby Magnum came along. Based on the 300 H&H Magnum, the 300 Weatherby delivers 300 more fps than its British cousin. Introduced in 1944, this is the all-around cartridge for the big game hunter.

    The best rifle in the market 300 weatherby mag.

  4. Never a worry

    By Torgy September 12, 2018

    I have been shooting Weatherby rifles for 21 years and I have never had one malfunction. I use my 300 with 180 nosler partion for elk and moose and all 8 animals I have taken have dropped without as much as a step.
    I hunt dear and antelope with my Mark V 257 Weatherby and that is the flattest shooting rifle I have ever owned. I like the 120 Nosler for that rifle.

  5. More Trophies with by Than any of my other Weathrby's

    By Ken January 22, 2018

    Simply stated the 300 Wby with Barnes Bullets will take anythng if the shot placement is correct. I have a 416 by; a 378; 338-378; 30-378 Wby and a 75 H&H. Fact: Every animal I have taken has been with my trusted 300 Wby h as been with a single shot including a 510 plus yard Barren Ground Carrbou Score 429-7/8; Southern Greater Kudu 185 yards Score 60" Ranked #32 Roland & Ward and SCI Both Trophies dropped on the spot. I have also taken a 8' square inland Grizzly with a single shot from my 300 using Barnes X bullets. 220gr at 186 yards. I could have used larger rounds but even at more than 500 yards the 300 takes any animal with a single shot. The only projectile I have recovered from the 300 was on the Southern Greater Kudu which I spined. The projectile a 200 gr Barnes X went through nearly 15 inches of solid bone and was protruding from the skin. It weighed 189.9 with all pedals intact.
