"Their bodies were blown up by AR-15s," he said. David Baum witness the Highland Park parade shooting. Just trying to point out that the 5.56 has limited hunting range for deer sized game and extending it 25 yards with a longer barrel is a worthwhile and significant thing.Dr. Not trying to give a lesson on hunting ethics. But it is a tragedy to maim game animals and have them go off and die suffering, or live with disabling non-lethal wounds or become coyote or other predator fodder. You can incapacitate an enemy combatant with non-lethal wounds. This is NOT a 300 yard deer rifle, and 200 would not be ethical with any but the very best bullets with absolutely an optimal shot angle and placement. The great drop off - loss of 20% of its energy in 50 yards is why getting a little more velocity is important, as it does stretch the effective range about 25 yards, maybe 50 more with a couple inches more barrel. pounds by only 100-125 yards, and to 800 by 150 yards. 5.56 ballistics fall off to less than 1,000 ft. Maybe as low as 800, if the bullet is a high performance hunting round like the Barnes TSX - solid copper that retains close to 100% of its energy, but expands violently and also has deep penetration, capable of breaking bone, if necessary. The usual criteria for ethical hunting of whitetail deer size game is 1,000 foot pounds of energy. When bad dude 400 yds away is poking his head out from behind a rock and you manage it get lucky and fire the round that smacks him in the forehead.he will be dead even if it was going a few hundred fps slower. If we are talking combat then you will find that the newer mil rounds remain lethal beyond the ability for most soldiers to make a good hit. Want even more range? Then you should consider changing platform and going to a heavy cartridge that is traditionally used for longer range hunting. 6.8 or 6.5 will still give reliable expansion sub 500 with the right ammo. If you want to be taking shots farther than that it is time to step up your caliber. Realistically if you are using 5.56 out of a 16" with quality ammunition your lethal range is well within what most would consider an ethical hunting shot (sub 300 yards). If you can keep retained energy higher at longer distance, you can increase your lethal hunting range. Retained energy has a substantial effect on lethality. The change in velocity of perhaps 40 fps per inch from 16 to 18 may have little effect on trajectory, but it has a much greater effect on downrange retained energy. You guys that don't hunt with 5.56 may be missing the point with dismissing barrel length. Looking at these threads, I'm sold that a 16/14.5inch barrel is fine. If i want to shoot past 500 yards, i use my. The high power space gun guys like a 24" for the long shots. Once the bullet goes subsonic it will wobble, losing accuracy. However, if you are trying to squeeze every bit of velocity out for very long distance shooting, long is better. That is why i sold my 18 and 20 inch ARs. It's why every time I look at a 223/5.56 velocity chart, all I think about is how on point my stance is that anything longer than 14.5 inches in this caliber is, for the most part, pointless.įor most shooting it is pointless.
