You are implying that CC's son is "...the nut behind the trigger".
That's not a very good way to convince those of us on this forum who've benefitted from CC's wisdom.
Perhaps you might try a nicer, and more courteous, approach.
Yeah, I know facts don't seem to matter and nobody wants to discuss those.
There aren't many "nuts behind the trigger" that haven't had things go sideways...and in about all those cases, its the nut to blame...not the rifle, not the caliber, not the wind, not an earthquake, etc. yours truly included.
Sure sounds like the case in CC description...you blame the caliber because the elk wasn't shot in the right spot. About like blaming a spoon for being fat...just doesn't make sense. I can assure you, that in 95% of the cases, shot placement is the issue, in the other 5% its a bullet issue...all of which are the fault of the guy pulling the trigger. Self reflection isn't easy, placing blame on something else, anything else, is wayyyy easier.
You shoot a bull elk in FRONT of the shoulder, I don't care with what caliber, and its probably going to be a chit-show. There seems to be a common belief that a bigger rifle compensates for poor shooting and iffy shot placement...its just not the case, except in perhaps fantasyland.
The three most important things to consider, when killing elk, again no matter the caliber...is shot placement, shot placement, and shot placement pretty much in that order, give or take. Somewhere after that...bullet construction.
I've tried it all...from .243 to .338 and about everything in between...69 elk later, head stamps and calibers mean a whole lot less to me than shot placement and bullet construction.
Still shake my head when caliber selection is blamed for crap shooting on game, funny stuff.
