We kill more gorilla in ND and SD with the 223 that we do with the 308 bullet 100 to 1.
The 223 has it place.
Semper Fe
PS I noticed the drop is signifcantly more 58 vs 42 feet for the two bullets.
long time gorilla hunter from South Dakota.
And you're right, the AR-15 (.223) has it's place - like the jungle & swamps, or as in Vietnam1 (which I believe I previously stipulated). And yes the heavier bullet will drop more (darn laws of physics again), but look at the 300yd ft-lb comparison; 620 for the .223 & 1144 for my 8mm - almost double the energy.
However, keep in mind that the intention of Stoner with his AR & smaller .233 round was to cause casualties - which would then theoretically slow down the enemy in tending to his wounded (IIRC taking 3 men out of a battle). While previously the idea was to kill the enemy; 30-06 '03 Springfield & M-1 Garand and .308 M-14.
BTW, that must have taken some time to post all that data - good job. And how you got the data for the .223 over 200yds is beyond me as Remington stopped there. Again, good job.
Oh, this fall I'll try North Dakota for Gorilla ;-)
1; That is once they went back to the originally spec'd clean burning powder which did not require a chrome receiver, issued cleaning kits and stopped the jamming/fouling problem.
