That's funny. We spend several years here listening to people complain Berger's failed to expand and went through like an ice pick, or just blew up shallow failing to enter the body cavity with lot's of good documentation, photos, recovered bullets etc.
A properly constructed bullet used as intended will do it's job and kill effectively as long as you use them as designed and intended barring some sort of QC issue.
Understanding how bullets are designed and constructed along with understanding the characteristics of your target and it's anatomy when deciding on an intended point of aim eliminate most of those issues.
If mono's were inferior at killing, they would not be so popular with professional dangerous game guides and hunters.
From what I've seen looking at literally thousands of carcasses is that most people either don't understand the anatomy or can't hit their desired aimpoint when they are guaranteeing, "I hit him dead on the shoulder".
A little too high hittig only the top of the scapula there's just not enough tissue to damage, too low and a bullet is likely to just pass through doing very little damage and may miss the lungs entirely.
Put it through or at the top of the heart and base of the lungs or through the spine with any quality bullet and they'll drop in their tracks or move less than a hundred yards.
It always cracks me up watching "shoulder shot" videos and seeing that if anything was hit at all it was just ribs high on or even missing the lungs which can result in even a deer running a very long way or just through the meat a little forward of the heart in which case they may well survive never to be seen again.
Most hunters need to spend a lot more time studying their prey and they bullets they choose to shoot at them so they can better understand how to be effective with them.
