Wondering if anyone has done some tests with some kind of gelatin or perhaps ribs and steak from the grocer to see if there is decent penetration at 200 yards, 300 yards, 400 yards and so on of the .223? Accuracy is great but the damage must be sufficient too. I recently saw some technical information on how the .223 drops off so much energy after a certain point and then isn't expected to penetrate a car door and effectively lay down damage on a person inside.
So, anyone do any tests like this? Would like to know how well the AR-15 would do with a bad guy out to these ranges and then with a little aluminum in the way (or even brush or grass which I hear can really screw up .223 even up pretty close compared to .308). Thinking of doing the ribs with meat behind it test soon all the way up to 500 yards.
Thanks in advance for the responses!

That'll be a fairly expensive experiment. Good luck to ya!

It will vary with the ammo, but first you have to get the HIT. Doing so, while under fire, on dodging, cover using men who are shooting back, limits MEN'S ability to hit to about 100m, and then most of the hits are "random", and not actually life threatening, (if treated) even if they are from 308's. To 200m, you can BET that any hit with a GOOD 223 sp will be at LEAST as likely to suffice as one with the non expanding types of 308, and peripheral hits will give an advantage to the 223 sp, because a 1" or more wide wound will naturally cause more and quicker blood loss than will the 1/2" or less diameter wound of a 308. Notice how NONE of the cops shot in the N. Hollywood bank robbery actually DIED, despite solid hits to limbs, and despite it taking nearly an hour to get them to the paramedics? They were hit with 30 cal ball rds. Ask varmint hunters what happens when 223 sp's hit coyotes and feral dogs! 1-2" wide holes get blown in them, that's what! However, the need for better penetration in men requires the use of the heavier, slower, less "explosive" types of sp's.

This testing is taking the situation in hand of not being under immediate fire and going for the longer shot that one couldn't make under pressure of bullets cracking by ones head. Just by looking at the numbers of how much energy drops off the 223 at 300 to 500 yards, it looks like it loses the ability to do the fragmentation tumble that causes so much damage. Then add in some kind of grass or very very light brush and the information that Chuck Taylor puts out shows the 223 will really lose it's effectiveness as the 308 keeps on going. The 308 numbers show it doesn't lose it's effectiveness in energy like the cliff drop off the 223 has. Anymore thoughts appreciated.
