Two of us used the 230 gr match target hybrid on Arizona cow elk last week.
My 85 yr old friend Don had a special permit called the Champs permit which allows him to shoot from the truck if necessary. We encountered five elk walking across a meadow at 300 yds while driving out of an area. Don was able to exit the truck, cross the road and shoot from a sitting position sending a 230 hybrid through both lungs. Sorry no pics of this one but entrance hole was caliber and exit was 1 1/4". Cow sort of stopped in her tracks then after a few seconds just teetered over. The rifle is a Browning A-bolt with a mag box of 2.8". The bullet velocity at muzzle is 2720 fps using RL-17. Impact velocity at 8000 ft was 2516 fps. Very impressive.
I finally connected several days later. A group of approx. 100 elk ran off an uphill slope that was comprised of nothing but burned trees. Upon seeing me they ran downhill through the trees with great haste. I couldn't shoot. Then I noticed some stragglers walked out. I figure they were so far up the hill they didn't see me and were simply following the others. One stopped between two trees at 247 yds offering a shot at the shoulders but little else. It was a high shoulder shot. The elk dropped like a stone to the shot.
Rifle is the previously mentioned 300 RUM with 24" barrel 230 hybrid velocity is 2975 fps at muzzle. At 8000 ft impact velocity was approximately 2800 fps.
There was considerable blood in the tissues around the shoulder meat. It is very difficult to see the exit hole. Exit on hide looked similar to Don's with a moderate hole. Once skinned the area was quite red with blood and the affected area was hard to see the damage. Once the shoulders were removed the damage to the ribs can easily be seen.
I won't know the extent of ruined meat till I clean the shoulders in a day or so. Just began cutting yesterday. I can take pics of shoulders in a day or so.
Here are the entrance and exit pics of ribs with shoulders removed.
