The best bullet for DRT is a bullet that hits 'em in the spine or the ear hole......after that, a lot of things can happen.
5-6 years ago a youngster shot a cow elk with a 270 cal, 150 NPt standing broadside at about 100 yds. She instantly collapsed. I figured the boy had spined her, but he hit perfectly in the armpit and the bullet went through both lungs and exited.
A day later with another 270 and 150 NPt I shot a trotting cow at about 50 yds. The bullet went through both lungs and landed against the hide on the off side. She traveled 100 yds before piling up.
A day after that my son with a 243 and 100 NPt shot a broadside cow at around 300 yds in the armpit. Bullet went through both lungs and exited. The cow immediately peeled out and disappeared into the timber, traveled about 30 yds before she went down for good.
Critters react differently. If you want DRT shoot them in the head..........
