I shot an elk once with a 180gr TTSX out of a 300 RUM at close range in the snow. The animal didnt show any reaction to the shot and ran off like I missed until it dropped. There wasnt a single speck of blood in the snow until we got to the spot where it died. The exit nor the entrance were noticable without digging around. Both lungs had a hole through them that was beyond caliber size, but not pulped like when hit with a Nosler BT. Interestingly the entrance side had a massive amount of blood shot.
