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. 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.

  2. newfoundland Canada moose hunt.

    By Jack March 08, 2017

    I shoot a Weatherby 300 mag with a 180 grain nosler partition bullet.last fall 2016 i shot a very big moose at 427 yards. one shot took out both lungs. this is the fourth moose i have taken with this gun, but the longest shot I am booked again for this fall 2017 would not carry any other rifle.

  3. Kodiak brown bear using Wby Mk5 with wby 200gr noslers

    By bob November 25, 2016

    I just got back from dream hunt, brown bear on Kodiak island. I used my 300 Wby Mark 5, and using Wby factory 200gr Nosler bullets. First shot double lung pass through at 100yds, bear dropped in his tracks. After a few seconds the bear managed to push up with his front legs. Second shot in the shoulder and he hit the ground dead. I could not have done any better than with this Wby combo.

  4. Excellent accuracy

    By Sherpa Dave November 07, 2016

    Model 700 stainless long barrel. This 165 gr ballistic tip matched to my gun so well I zero to 250 yds. Just took an extra large BC mule deer at 150 yds. Bullet mushroomed perfectly , caused a four inch hole at entry and set against the hide at exit. Excellent performance over all.

  5. Colorado Elk; 609 Yards Quartering Away One Shot

    By Rjsounder October 31, 2016

    Excellent ammo 180 grain Accubond quartering away shot entered left hip high, shattered the spin, blew out the diaphragm, right lung and exited the front right shoulder leaving a 3" diameter exit hole. Did not find the bullet. A true 800 yard elk killing bullet in this caliber.
