This is just my experience over the past 3 years July 2024-November 2026. I have 8 driven hunts and a fallow deer hunt in Gylaj in Hungary in the next 3 months. Hopefully another 10-20 animals are on the hunt.
5 Red Deer, 4 stags and a hind. All shot with monometal bullets from RWS Hit. Kind of a like a Barnes Tipped X Bullet. Cartridges were 308, 30-06 and 10,3x68. The 2 shot with the 10,3x68 were shot in the heart and ran 40-60 meters. The rest were shot through the shoulders or spine and were dead with 20 meters.
1 wild boar shot through the lungs too high and ran 150 meters, killed by the dog handler. Was not able to move, but wasn't dead.
4 fallow deer. 1 with the 308 Winchester, 2 with the 8x57 and 1 with the 10,3x68 RWS, all with RWS Hit bullets. 3 were shoulder shots, down at the shot, 2 were dead when I got there. 1 was a heart/lung pocket shot ran 100 yards.
2 chamois. Both with a 30-06 RWS Hit. One lung shot laying down, ran 40 meters. One shoulder shot dead in 20 meters.
6 roe deer. 2 RWS HIT heart/lung shot ran 30-60 meters with 8x57. 1 same cartridge combination shot through the shoulders dead on the spot. 3 with 6.5 Creedmoor Hornady ELD-X. Shoulder shot dropped in tracks.
18 animals in 3 years, not a ton. Mostly with the RWS Hit.
Cartridge did not matter, bullet placement mattered on 18 animals.
Tough bullet in the shoulders.
Soft bullet in the heart lungs was ok, but not as dramatic.
Bad shots mean tracking.
Nothing else really matters.
I am convinced a 223, 243 or 6.5 Creedmoor with an accurate rifle and a good bullet in the spine, lungs or heart will kill anything that walks.
