The current world record typical elk taken in AZ in 1968 by Alonzo Winters was taken with a Savage Model 99 in 300 Savage. The record before that taken in CO by John Plute in CO in 1899 was taken with a Win Model 1895 in 30-40 Krag. What worked on those 2 bulls will also work today. Elk are still elk and they ain't bullet proof.
