Two years ago, the last time we were drawn for elk, my older friend Don (85) got a cow elk at 300 yds with his 300 WSM using the 230 gr match target hybrid. Vel at muzzle was 2720 fps. Double lung stopped her and within a few seconds she just keeled over stiff legged and died. Exit was approx. 1 1/2".
I shot a huge cow at 250 yds with a high double shoulder shot in thickly wooded slope where there was a burn. Same bullet from 300 RUM vel 2975 at muzzle. The elk folded instantly DRT. Exit again around 1 1/2" dia.
A friend went to AK and shot a huge moose with his 300 RUM and the 230. He said it exited. He also used this package to shoot an aoudad at 635 yds in a strong crosswind of 12-15 mph. I saw his video and was another DRT. Exit hole looked small but who cares it stoned the critter.
