The .416 Weatherby Magnum
By Chuck Hawks
The .416 Weatherby Magnum was introduced in 1989 to out perform the earlier .416 Rigby and the upstart .416 Remington Magnum. This it does, by a considerable margin, in true Weatherby fashion, using a belted case based on the .416 Rigby with a Weatherby double radius shoulder that is loaded to much higher pressure than the .416 Rigby.
Weatherby offers a 350 grain Barnes X-Bullet at 2,850 fps and 6,312 ft. lbs. of ME, a 400 grain Swift A-Frame bullet at 2,650 fps and 6,237 ft. lbs. of energy, and two 400 grain RN bullets at 2,700 fps with 6,474 ft. lbs. of ME, a soft point and a solid. The figures for the 400 grain solid bullet at 100 yards are 2,411 fps and 5,162 ft. lbs.
The A-Square reloading manual Any Shot You Want suggests, among other loads, 116.0 grains of IMR 7828 powder for a MV of 2632 fps, and 120.0 grains of IMR 7828 for a MV of 2742 fps, both with a 400 grain A-Square bullet. These loads were assembled using A-Square brass and CCI-250 primers, and were tested in a 26" barrel. The MAP of the maximum load was 61,000 psi.
