Perhaps one could ask the following hypothetical question.
You are going to get shot at one time.
There will be an ambulance team and a surgical hospital waiting to try to save you within seconds of the shooting.
Which caliber would you choose to get shot at with?
The 223 or a 338?
Either will give you a non-survivable wound, no matter the medical help available.
Seriously, you're approaching the take-a-knee level of stupidity here..
