I do not claim to be an expert, because I have only one bull moose kill under my belt and that was last year. I was using a .270win with 140 gr Berger VLDH bullet. My shot was only at about 75 yards and I put four well placed, rapid shots behind the shoulder. My philosophy, since I have killed several elk, is to shoot them to the ground. He was probably dead with the first shot but he took about four steps before falling over. Upon closer examination, not one bullet exited. 4 entry holes only, but his lungs looked like they had gone through a blender. I hear that Berger bullets are best at long range and I definitely was not thinking I would get a shot at 75 yards, but you take what you get. I question, if that bullet was the best choice. I regularly use 140 gr. Accubonds on elk with great results, and even killed an elk with one shot with my 130 gr. ballistic tip, because that was all I had loaded up after deer season. Depending on likely shot distance, I don't think I will be using Bergers again, because, I have been a bow hunter most my life and I always seem to kill stuff and close range, even with a rifle. My longest kill with a multitude of game is 365 yards but most under 200 yards. Just food for thought and best of luck on your hunt.
