My neighbor had one and after disaster after disaster,moved up in caliber...I agree with tshunter58...It is not an all around Elk caliber and by all around,I mean taking any shot that will get to the vitals as Elk hunting goes.
Broadside only or head shots..Most any caliber/bullet works.

sounds like your neighbor needs to learn how to shoot and spent more time at the range if he keeps crippling Elk. Going up in cal doesn't make up for poor marksmanship. The 243 or 6mm will kill any Elk if you shoot it straight.
