HG talk typically begins with the number of energy and ends with brand loyalty. The issue is that defensive shootings do not test the passion, but only the possibility of a bullet to hit something essential, consistent labor over clothes, and allow the shooter to make fast and accurate follow-up fire.
Tradeoffs are even more difficult to overlook with modern testing. The standard reference is still the 12 -18 inches of penetration in ballistic gelatin since shallow penetration may miss the vital organs whereas over-penetration may cause additional risks beyond the target. The yardstick does not choose a better cartridge, but it does give attention to the rounds that habitually require too much compromise to be effectively used at home in self defense.
1. .22 Long Rifle (.22 LR)
Low recoil and low cost practices are the advantages of 22 LR that ensure loyalty, but the ignition of the rimfire is the main weakness. Since rimfire is by nature more prone to failure than centerfire, and any stoppage is magnified by small semi-autos with less generous feed geometry. It does not matter how the reliability may be handled using a better quality of ammunition or rigorous maintenance the defensive handicap of the cartridge is terminal performance, which often can not be pushed to a 12-inch minimum when obstacles and imperfect angles are involved.
2. .25 ACP
25 ACP was designed to fit a previous generation of pocket pistols and the round has been caught up there since. Muzzle energy is usually so low that the current hollow-point design has little velocity to play with, and most platforms in the.25 ACP chambering are sparse in sight and strength. What would be produced is a cartridge which has a propensity to have little penetration potential and guns that cannot be shot effectively under stress.
3. .32 ACP
The ACP finds itself in an uncomfortable middle-ground: it is softer than snappy micro-compacts in larger calibers, but will remain often unreliable in expansion and marginal in penetration as soon as heavy clothing is involved. Culture The culture of testing has consistently demonstrated that fabric may fill in hollow points and alter their behavior. When a cartridge is launched with a high level of momentum close to the floor, such differences can be the difference between sufficient depth and a deplorable short-stop.
4. .410 Shotshell From Revolvers
The engineers offer 410 revolvers with a shotgun effect in the size of a handgun, but the engineering is not so fairy-tale. Velocity is reduced by short barrels, which also introduce unpredictable patterns, rifling may create erratic patterns, and the typical buckshot load is not expected to reach the same depth as that of defensive ammunition. Most of the platforms also introduce a moribund weight to capacity ratio big cylinders and frames on five shots to do so without providing the predictable point of impact control that is necessary to predict the exact location where the shot will hit. Specialty.410 loads of handguns have been available, but the overall problem is: patterns that diffuse and penetration is inconsistent that makes it difficult to hold people accountable within rooms and corridors.
5. .380 ACP When Loaded Light
It is true that 380 ACP may work, but many shooters would not guess how sensitive it would be to the choice of ammunition and barrel length. With short-barreled pistols, a few of the typical loads exhibit the archetypal failure mode they either flatten out and under-penetrate or they penetrate satisfactorily but do not expand beyond heavy fabric. The same split of either/or is evident many times in heavy-clothing gel testing using short-barreled pistol. The cartridge margin is minimal, and small margins are where poor choice of load is a home-defense issue.
6. .38 Special Out of Ultra-short Barrels
There is still a role of 38 Special, though even the smallest snub-nose revolver turns it into a different cartridge than the box suggests. Speed is lost quickly, and the speed is frequently compensated by irregular growth–particularly by cloth. The gel work in the revolver of Lucky Gunner showed that 12 of 18 test loads of .38 Special were not able to expand at least one of the bullets through a heavy barrier of clothing, and 5 would not expand whatsoever. It does not necessarily condemn all .38 loading, the reason being that it is why just carry a snub may turn out more complex than custom dictates.
7. 10mm Auto
10mm Auto provides the real performance but home protection is no scorecard of the highest number of foot-pounds. Most shooters use high recoil and blast follow-ups are slow and harder loads are more likely to punch through typical residential products when the shot misses or the bullets are not expanding as intended. The cartridge is also likely to drive most shooters into a training deficit: with the gun feeling like work, it gets less practiced, and the skills are lost in areas where they are needed most; the speed and accurate on-command.
8. .44 Magnum
44 Magnum has a putting-room stock, but within a house that putting-room stock is with great recoil, a gradual interval between shots and a severe over-penetration characteristic. What makes it a good hunting cartridge in deep driving can be counterproductive when it comes to the realities of close quarters, where quick and repeatable hits and controlled risk that is not on the target are highly valued.
Home defense never favors excesses. The practical way is the middle way: a centerfire cartridge whose consistency in penetration, dependability in working in the chosen firearm, and recoil which permits accurate strings, since in handguns the actual mechanism remains in the placement of the shot supported by adequate depth.
