Seems it may be somewhat of an art, fine tuning loads with bullet type and velocity. Some Hammers can be pretty expansive. Googling “Types of Hammer bullets” will give details.
Your load combo was evidently pretty expansive and seems bone was affected. Even Barnes can be pretty expansive at high velocity.
Some years ago, I shot a WT with an 80 gr TTSX at 3,600 fps out of my .240 Wby. Huge blast effect on the chest wall, a not so impressive pass thru the chest cavity.
Speed kills, but matching bullet type with speed seems more important to me now than earlier.
