Gun Control & RKBA

Troy sounds pretty knowledgeable on it, albeit dated:

Troy [Site Staff] 9/25/2005 10:38:49 AM EDT ... A military 5.56 FMJ loading like M193 will cause larger wounds than a military .30-06 loading like M2 ball, at least at close range. This is because the 55gr FMJ M193 bullet will fragment (out to a certain range), while the .30-06 bullet, with its thicker jacket, will not.
Thus, comparing strictly commonly-available MILITARY loads, 5.56 is the better performer. But in a broader scope, this is an exception.

Comparing the best performing (for human combat) 5.56mm round (arguably the 75gr Hornady or 77gr Nosler) vs. the best performing .30-06 load (155gr Hornady), the .30-06 is a *substantially* better performer. -Troy https://www.ar15.com/archive/topic.html?b=3&f=16&t=251175
