Below is a Canadian Grizzly Bear shot with a .300 WSM. Hazel used the 180 grain A-Frame loaded to 2950fps. Range was 60 yards, the boar was just disappearing into the Alders on dark, quartering away. Hazel picked her angle perfectly (see bleeding around the entry wound), taking the snap shot from a kneeling position.
The A-frame performed flawlessly, the bear was anchored where it was shot, the bullet destroyed the vitals, coming to rest against the front of the offside shoulder. Bullet weight retention was 176 grains. Weight of bear approximately 190kg (420lb). Length of animal 6 foot.
Below, note the larger than caliber entry wound. The A-frame will often do this at close range / high impact velocity. This also occurs with the Swift Scirocco from time to time. Large entry wounds show that the projectile is expanding quickly and dumping vast amounts of energy. This can of course also occur in cases of surface bullet blow up, however, this certainly is not the case with the A-Frame which delivers deep trauma for fast killing.
