From butchering animals shot with a 270. A deer shot through the shoulders within about 100 yds with a 130 gr 270 - the far shoulder is disgarded !! The high velocity ruptures tissues over a large area .The more fragile the bullet the more damage also. A 12 Ga slug is going much slower and doesn't have the same effects so will usually just punch a 12 ga hole through the animal. Handgun rounds have the same effect as the 12 ga.
