My 17 year old brother shot a bull this year with a .243 using a 95 grain slug. He dropped it with one shot and he didn't move an inch after he hit the ground. I would not hesitate if you feel confident in your shooting ability, but isn't that how it should be with all calibers?
There is no doubt a .243/6mm bullet can kill an elk � that has been proven many times.
Best choice for most people/situations? Nope, not even close IMO.
Since I started hunting elk in 1982 I have seen more elk wounded and lost by hunters using a .243/6mm than probably all other calibers combined. A .243/6mm wouldn�t be my first choice.
