"My old dad used my rifle to finish off a 6x6 he'd wounded with his 338-06. It was almost dark and the bull was ambling straight away probably 100 yds. or so distance. Dad hit him squarely in the tater hole/anus with a TSX, the bull took a few more steps and flopped over, dead. The bullet traveled from the anus to the front of the right shoulder, under the skin, where we found it when skinning the bull-"

I'm trying to figure out in what scenario a .338-06 is not suitable to finish a job but a Whelen is? confused
