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.

  1. 650 yard Whitetail

    By Bigshow November 13, 2017

    I have hunted with my 270 Weatherby forever and thought I would never change until I bought my Mark V 300 Weatherby! Love this rifle and hunt anything and everything with it. Shot a 145 inch 10pt year before last at 650 yards. He dropped so fast I thought I missed him!

  2. Simply the Best

    By rico13753 November 04, 2017

    From an Oxbow,Maine Black bear to a pair of pretty fair Elk in Flagstaff, Arizona, and least I forget my Moose in Newfoundland, the 180 grain Spire Point is as good as it gets for my 300 Weatherby Mag! I love this bullet and use it here at home for deer and extremely long range chucks. One shot, one dead critter!

  3. Bought for Elk, but Hammer on Whitetail!!

    By Zem October 15, 2017

    Bought my Weatherby Vanguard in 300 WBY MAG about 15 years ago with hopes of an elk hunt in the Northern Rockies - That trip never happened. About 3 years ago, I decided to use it for local deer hunting (South Louisiana). Shooting the 180 grain Nosler Partition that it was sighted in for, I’ve yet to have a deer take a step after pulling the trigger. This thing hits like a sledge hammer, and the Partition bullet doesn’t produce large exit wounds that destroys meat.

    Many comment on the cost of ammo, but when I tell them that I’ve NEVER had to take a second shot or follow blood trails, they get quiet quickly.

    A friend of mine was invited to a Colorado elk hunt last year. He told me that he planned to use his 30-06. I offered to let him borrow my Weatherby, which he did. He saw one elk on his trip - A 6x6 broadside at 485 yards. He dropped it first shot! He said that he’d never had tried that shot with his 30-06. He recently bought a Mark V in 300 WBY MAG, and sighted it in with the same round.

    Accuracy- What I can do to a 200 yard target is mind-boggling! I’m sighted in at 200, and every year prior to taking it hunting, I’ll go to the range just to “make sure” it’s still zeroed. Yesterday I put 3 shots inside of a quarter-sized area (~1/2-MOA)!! This gun with Weatherby ammo is more repeatable than I am! If you miss, you can’t blame the gun / ammo!

    “Overkill for Whitetail”- So many folks that make this comment shoot a 30-06. My response is that we’re shooting the SAME bullet, mine is just moving faster (500 feet/sec faster!), and at 200 yards, has 1,100 more lb/ft of energy! It also drops 30 inches LESS at 500 yards.

    When Weatherby makes their famous statement, (Nothing shoots flatter, hits harder, or is more accurate.....), it’s not a marketing gimmick- My experiences are living proof. What more could you want for medium / big game hunting?

    While most other gun manufacturers have changed ownership through the years, Weatherby is still privately run, and has not lost focus of Roy Weatherby’s original “vision”. I’m a Weatherby shooter for life!!

  4. Hard hitting accuracy

    By KBaker October 05, 2017

    I have two Weatherby rifles. My 300 and the 257 Weatherby mag shoot spot on with Weatherby Ammo. The ballistic chart is accurate to the inch. If it says your shot will be 7.7 inches low it will be. Can't ask for better than that!

  5. Great gun and cartridge

    By Brittany Man April 21, 2017

    Yes ago I purchased a Weatherby Alaskan in 300 WBY Mag, It loves the 165 grain spire points WBY ammo.. I took an antelope at over 325 yards and it never moved. It dropped like a stone.

    I would like to try the 165 grain ballistic tips. I have used ballistic tips in the past on ground hog and deer with great success. They are very accurate.

    I have set up my Weatherby with 2 scopes. Both are Leupolds with quick release rings. One scope is a 2.5-8X and the other is a 6-18X.

    I used this rifle to harvest a Texas deer. Was a clean humane kill like the antelope. While on the Texas hunt I also shot a hog at night while it was on the run with the 6-18X scope set at 18 power. The guide lit it up with a spot light. His helper thought I missed the hog, but I heard the thump when the bullet hit it.
