What's the most lethal automatic caliber and load I can use for home protection ?

Question

I already have a .357 magnum running 125grain hollowpoints, but I need an automatic too. I have many enemies.

Answer 1

The best home protection weapon is a pump action 12 gauge shotgun. You don't even have to load it, if you don't want to. No matter what language you speak or understand, or even if you have never heard one, when you hear the pump of a 12 gauge chambering a round, you will know what it is. It is hard to keep your mind on breaking in a door when you know a 12 Gauge with 00 or 000 buck is waiting for you!!! Ithica makes one model that switches between pump and semi-automatic and even offers a clip instead of barrel loaded. If all else fails and you are unloaded or out of ammo, the weapon can deliver an awesome "butt-stroke to the head" (or other body part).

A shotgun also has two other big advantages. Many types of shot, such as triple 000 buckshot are less dangerous to people inside your home behind other walls. A .357, .45 or 10mm might easily penetrate other walls if you miss (or in some cases, even penetrate the intruder and still go through another wall). The shotgun has a lower velocity and slightly less penetration. On the other hand, there is a lot more lead heading in a single direction and you don't have to worry alot about aiming as aiming "close enough" counts with a medium choke at close range.

If you don't like that answer, Colt Delta Elite 10mm has double the knock-down power of a .45. If you can still find one, be careful and inspect often, as these had a severe problem with metal fatigue and cracking after much use.

Finally, if nothing else works for you, consider hand-loading. There are so many different types of powder and so many types and shapes of bullets that you can custom load something that works best for you (I hope, within the safety limits) The cut and size of the powder determines how rapidly it burns, but case size also determines the volume of powder that you can place inside a casing. The downside is, if you don't know what you are doing, a small amount of the wrong powder can blow up a weapon, where as a case full of the wrong powder can do no more than a cap gun (and different amounts of different powders can do everything in between). Good handloading books have tables that will help you determine what loads work best with various bullet types, but if you have never handloaded before, check out some friends with experience first. Check out any gun range in your area and I bet at least one person you meet there handloads. Most of us "Gun Nuts" are always happy to help others in areas new to them. Remember, that if you reload on the "hot" side, your weapon might fatigue or even fail sooner than normal and there is always a chance that the shooter may incur a fatal injury from loading too hot.

Retraction: After review, I realized I mistated that 000 Buckshot is smaller than 00 Buckshot, which is not the case. In any case, you need to choose the shot that works best for you. 0 or 1 buckshot might be better if you have thin walls, but I still avoid 00 buck or larger indoors.

Answer 2

10 mm expensive but worth it, with a hot load you are replicating .357 Mag performance. As far as being cost effective and recoil managable get a .45 ACP

Or go all the way and get a Desert Eagle and let the .44 Mag or .50 AE rip.

The "most lethal" would be a reliable firearm with HIGH capacity as long as you can get a head shot with every round. For that look into a FN Five-seveN.

Answer 4

For home defense, nothing beats a 12 gauge with magnum 00 buckshot shells.

Of course that doesn't help you on the street. A really good arm, if you don't mind Glocks, is the Glock 20. The 10mm cartridge is almost as powerful as a .357 magnum, you get 15 shots, and reloading is fast as the gun is an automatic.

12 gauge ($300) + Glock 20 ($525) + 2 extra mags ($60) = Priceless

Answer 5

Not to sound like a smart @$$ but, the most lethal bullet it the one you can shoot well and into a vital area. Some creatures die from being shot with a .22 rimfire. Some creatures survive a hit from a 30-06. It's really more about bullet placement than gun or caliber. Practice all you can to develop your shooting skills.

Since you already have a .357, have you considered a rifle of the same caliber? It simplifies ammo. A Marlin 1894 357 mag is much more lethal than the same round fired from a pistol.

Answer 6

the 50 cal
nothing beats it awesome stopping power
45 auto is tops
357 has one of the best stopping percentages for a revolver round
if you can find an older 357 based desert eagle you have what you want
other than that a 12 guage magnum with pistol grip loaded with 000 buck and a tact light is the bomb for home invaders

Answer 7

the hardest would be the 50cal desert eagle but its probably not good for home protection. i suggest 45acp if you want a semi. better yet, why dont you get a semi auto 12 gauge shotgun, that would be the most "lethal".

Answer 8

you can get an auto in 45 cal. and also in 44 mag. good luck..

Answer 9

A propane tank an a match, then you wont have to worry about your enemies.

A 105mm with six charge bags. Nut!
