Determining the maximum effective range of the 5.56×45 is easy. Minimal research will point you toward military resources. It makes sense given the 5.56’s pedigree as a military\/NATO cartridge. In this case, we simply open up a copy of the US Army Technical Manual 9-1005-319-10<\/a>\u00a0(which covers the M16A2 rifle and the M4\/M4A1 carbine), turn the pages to effective range, and you will find these data:<\/p>\n\n\n\n\n\t\n\n\t\n\t\n\t

5.56 Effective Range: Department of Defense<\/h2>\n

According to the US Department of Defense, maximum effective range is the \u201cthe maximum distance at which a weapon may be expected to be accurate and achieve the desired effect.\u201d<\/p>\n

To make sense of the above data, the 5.56 is practical for engaging a single target at 602 yards when fired through a 20\u201d barrel. That’s about 547 yards in the case of a carbine\u2019s shorter 14.5\u2033 barrel.<\/p>\n

Of course, the \u201cdesired effect\u201d in the Army\u2019s case is the production of a disabling wound in an enemy combatant\u2019s body. The Army has determined that a disabling wound can result from impact energy as weak as 60 ft lbs. The basic M193 cartridge<\/a>, which has a 55 grain bullet and muzzle velocity of 3,250 fps, can deliver that much damage at around 1,425 yards. (Actually being able to hit so distant a target is another story \u2013 hence the inclusion of the phrase \u201cmay be expected.\u201d)<\/p>\n

You may only wish to hit a paper target. General consensus holds that the 5.56 can consistently group shots at 1,000 yards. This is assuming you\u2019re using good ammo under ideal conditions \u2013 and also that you\u2019re not some ham and egger who just picked up a rifle for the first time last week.<\/p>\n

Civilian Effective Distance<\/h3>\n

\"Firing<\/p>\n

Let\u2019s dig a little deeper into what the 5.56\u2019s effective range looks like. General consensus also holds that the minimum impact energy required for self-defense is between 220 and 300 ft lbs. 260 ft lbs, the average of those two numbers, is a realistic threshold to consider suitable for personal protection. The minimum impact energy considered ethical for hunting whitetail is far greater at 1,000 ft lbs.<\/p>\n

We calculated the distances at which a variety of 5.56 ammunition<\/a> can deliver those two amounts of impact energy in this chart.<\/p>\n\n\n\n\n\t\n\n\t\n\t\n\t\n\t\n\t\n\t\n\t\n\t
<\/td>Muzzle Velocity (fps)<\/th>G1 Ballistic Coefficient<\/th>1,000 ft lbs Range (yds)<\/th>260 ft lbs Range (yds)<\/th>\n<\/tr>\n<\/thead>\n

Hornady 75gr Interlock<\/td>2321<\/td>0.234<\/td>--<\/td>370<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n\n

(It\u2019s important to note that not all of these bullet types are suitable for hunting \u2013 especially an FMJ. Full metal jacket bullets<\/a> don’t expand significantly in soft tissue.)<\/p>\n

Data Based Conclusions:<\/h4>\n
    \n
  1. Self-Defense: Like the Army says, the 5.56 is effective for self-defense well beyond 500 yards. Whether you can even consider a target to be a threat at that range, however, is another matter altogether.<\/li>\n
  2. Hunting: The 5.56 consistently fails to deliver 1,000 ft lbs of energy beyond 100 yards. This is not to suggest the rifle is incapable of anchoring a deer, especially with a well-placed shot, and the right bullet. Of course, few ethical hunters would agree the cartridge is appropriate for long-distance deer hunting.<\/li>\n<\/ol>\n

    Let\u2019s conclude by expounding on the 5.56\u2019s suitability for self-defense. It is an intermediate cartridge, specifically designed to cover the maximum typical engagement ranges encountered in modern combat. The average person engaging in home defense will not have to cover a range greater than the length of the largest room in their house. In fact, that’s really all the farther you want the projectile to go, typically.<\/p>\n

    If you\u2019re worried whether your AR-15 is capable of incapacitating a home invader, set that worry aside. The 5.56 (and 223 Rem) is positively overpowering at close range.<\/p>\n","protected":false},"excerpt":{"rendered":"
