That is an interesting question; i like it. I, however, cannot answer your question.

Myself, i wouldn't use the 270g bullet on Elk by choice. My first choice would be the 300g Nosler Partition. If i were loaded with 270g bullet, and an elk presented a shot, i would take it, and it would certainly work. Once whilst deer hunting, we saw elk only a few mile out of Missoula; i killed a 6 point bull with an 80g 6mm bullet. However, an elk hit with a 100g 6mm partition shows more sign of being hurt. An elk hit with a 160g 7mm bullet shows even more sign of being hurt. Most of the Elk i killed fell to a 225g partition, shot from a 358 winchester; i really liked how that bullet hurt them elk.

Here comes a stupid opinion. Three milk jugs does not equal an elk, but 4 jugs may come close, if the bullet hits lungs. Just one fella dumb opinion is what that is.

For elk i recommend the 300g partition. If one doesn't have any of them extinct bullet, perhaps the 300g XTP Magnum is a good choice. Of course a conical shot out of my X7 without a qla, would surely do the job.

The 270g Deep Curl works for me. It really really smucks deer. It is accurate in my rifle. It is inexpensive. It is available.
