I've taken 4 bulls with archery myself, since We're on that topic archery hunting is leading to a huge number of wounded and lost elk in my area.
I've done it myself, hitting a little high or clipping the scapula because a leg was positioned back covering the vitals.
We find dead bulls after archery season every year, it's really soured me on archery so I went back to rifle last season.
You're either ignorant or just biased beyond belief.. I suspect a little of both.
I know a heavy 30 cal will anchor a bull if shot in the hind quarter because I've done it, a friend made a shitty shot on a bull with a 243 (I don't hunt with that clown anymore) and I drilled him in the femor before he made the timber.
That bull dropped instantly, the 180 partition from my 300 WM shattered the bone and penetrated into the liver.
I don't think anyone should upsize their caliber in the belief that it's a substitute for skill, I've certainly seen the guys who shoot a few rounds from a bench once a year and call it good.
I have no problem with guys taking reasonable short range shots on elk with small caliber rounds, but denying that faster heavier bullets of equal construction don't wreck more havoc is like saying cow farts cause global warming
You have to be ignorant as fuck to be telling me that your wm will anchor them because it them in the hind quarter
