I have seen elk killed with a .243, my opinion, not enough gun unless you can consistently hit them in the head at 100yds. Give the animal a break! They deserve more respect than that. A clean humane death if you are going to do it.

I don't recall Bob consistently using a 25-06, and if he did he was an excellent shot and held his shots to close ranges. He was an advocate of a 30-06 and all those contenders.
