Lots of very good advice and bullet placement is at least 99% of any kill. Having killed a large number of elk and deer with the old 270 factory 130gr core lock bullet prior to the new wonder bullets the animals went down hard. Regrettably I too was bitten by the bigger is better bug and went through the big magnums and premium bullets (kept the premium bullets). As a old guy, I am back to shooting the Nosler Partition in 270 and 7x57 and animals keep going down. I will not shoot at anything over 400yd. as I do not wish to wound a game animal. This years spike never knew what hit him.
