I'm shooting them out of a 10 twist as well.
Went out a few days after Christmas on my cow hunt. When my opportunity came it wasn't really a long range shot but when it comes to elk I'm not going to pass up a good shot hoping for a longer one. Found a large herd, somewhere about 100 head. Waiting until I could get one of the larger cows separated off to the side. Ranged her at 394 yards, dialed up 4.0 MOA on my Nightforce leaned into the deadfall I was using for a rest and eased one in right in the crease of the shoulder. As I recovered from the recoil and got her back in the scope she took two jumps forward and went down on her front end kinda skidding through the snow and regained her feet disapeering into the swarming herd. I watched the herd for a bit with my binos as they milled in a ball looking for my cow. After a couple minutes they started to ease off and since I couldn't see one that looked sick I started looking off to the side of them and immediately saw the rear end of my cow lying on the ground facing me. While I didn't see her go down she did not travel more than 20 or 30 yards from the shot. 215 Berger Hybrid entered right in the crease behind the shoulder and exited near the back of the rib cage on the far side leaving a tennis ball size hole taking out 2 ribs in front of the last one. That transect just destroyed the lungs and perforated the diaphragm causing massive internal hemorrhaging that filled up the body cavity on both sides of the diaphragm with blood.
I've killed quite a few elk with the same shot placement using traditional bullets like Nosler Partitions and Winchester Ballistic Silver Tips, etc and had very similar results. I've now killed 3 antelope and an elk with the 215 Berger Hybrids and have total confidence in them. All shots have been between 200 and 538 yards so far and all had what I would call "normal, expected" size exit holes. I am totally sold on these as North American big game hunting bullets. All critters were DRT 9 within 20 - 30 yards). gun)
