I feel the 270 will do just fine, as long as you 1. Take a good shot (no texas heart shots) and 2. Use a good stout bullet.
In 02 I was elk hunting with a guy who brought down a small racked 5x5 using 140 grain corelokts from his 270. Two shots. Both went through the right rear ham and ended up in the chest cavity at about 80 yards. The bull ran about 100-120 yards.
This year I brought down my 6x6 with my 7mag with 160 partitions. Dropped him dead in his tracks. Shot perfect, 1/3 way up from belly directly behind shoulder.
My friends this year also got huge elk (6x6 & 6x7) with 30/06's. One used 180 corelokts and the other 150 corelokts. Each required 2 shots. Their shots were about 35-40 yards each and both were into the chest cavity.
This was in New Mexico, unit 16C.
