Not 25-06, but the bullet on the right below is a 95gr SST that my son used on a frontal shot on a deer with his .243 Win at very close range 4 years ago when he was 14. Impact velocity was about 3,000 fps. It went through about 2 feet of deer and ended up under the hide toward the rear.
About 50 minutes later, his younger brother shot this guy with a shorter-barreled .243 Win with Hornady Lite loads. 87gr SST impacting at about 2,400 fps and exited.
Both deer dropped in their tracks.
Entrance wound:
