I have used the 124 Hammer Hunter out of my 6.5 WSM (MV about 3200fps) the past two years on cow elk. The 2021 cow was broadside about 100 yards away, hit behind the shoulders and made a 30 yard dash before collapsing in the trees. The bullet exited leaving about a 1" exit hole, The 2020 cow elk was also shot about 100 yards away and broadside. The bullet entered through some muscle on the back of the shoulder, though an onside rib, though an offside rib and scapula, and exited. She ran about 40 yards. Meat loss was minimal around the bullet path. One of the petals of the all copper bullet was found under the far side hide. As the gutless method of dressing was used, the internal trauma was not checked.
