You should be looking for a 270 or bigger.
30 caliber, 165 grain or bigger...
Lets not play games , be an ethical hunter and use an appropriate cartridge.
For all conceivable situations.
We cannot always depend on a perfect broadside shot and perfect shot placement.
We should be clear that a .243 will kill any living thing on earth...
IF it is well and appropriately placed...
BUT... when a hunter exceeds his skill level, and/or the limitations of the rifle/cartridge... he is being irresponsible...
The arguments against the .243 are exactly applicable to the 25-06, .27-06 and can even be applied (albeit lightly) to the 30-06 which the majority of
AVERAGE hunters should consider the
MINIMUM for Elk and Moose etc.
The .270 and down, should be left to the expert marksmen and the very self-disciplined hunters who refuse to take the less than desirable shots.
I really trust the 30-06, 165 grain premium type bullets. (Vital-Shok Accubonds) to perform well in all situations... including irresponsible 400 yard neck/head shots.
Just last year I witnessed a 200 yard head shot that went through behind the spikers eyes... he ran blind for about four hundred yards and died slow...
NOW THAT'S IRRESPONSIBLE... even for Annie Oakley!!
NO the .243 should absolutely
NOT be recommended for elk...because elk bulls can reach 500 to 1000 pounds and sometimes bigger!!! They are extremely hearty and often run substantial distances after being
well hit...
Hell, if you wanted
JUST to kill them, you could use a .22 LR with a head shot at the lofty distance of 100 feet...
but you'd seldom find the carcass before the meat spoiled!
Not every elk is a cow, or yearling bull... or even standing still.
