Default Should 22Mag be Taken Seriously as a Defensive Caliber?

Hello Everyone, while browsing the Internet, I came upon an article which has sparked an interest in me regarding taking defensive measures should it come to that point.
Here is the article: Should 22Mag be Taken Seriously as a Defensive Caliber?
Depends on the barrel length.

Now, I would like to start a discussion regarding the viability of a 22 wmr rifle as a Defensive weapon vs. .223 through .308 etc.

Given the price & availability of ammo, would this caliber make sense ?

Although the .22 wmr is a lethal round, the fact that it is a rimfire round and therefore inherently less reliable than a centerfire round makes it questionable for self defense.

Would I use .22 wmr if it was the only round available? Yes, however, it is well down my list of preferred SD ammo.

When it comes to .223 rem. or .308 win., there is a large gap between those two rounds in velocity and muzzle energy when compared to .22 wmr. Throw in the reliability question and, IMO, the answer is clear.

Here are some numbers I found online: (not an exhaustive search!)

.22 wmr : 37 gr. - 2000 ft./sec. muzzle velocity, 342 ft./lbs. of muzzle energy
.223 rem.: 55 gr. - 3300 ft./sec. m.v., 1209 ft./lbs. m.e.
.308 win.: 150 gr. - 2820 ft./sec. m.v., 2648 ft./lbs. m.e.

Accordingly, if the funds and the platform are available. .308 is by far the best choice for a static SD situation, .223 rem. may be preferable in a situation where one must be mobile, and .22 wmr comes in a distant third, IMO.

I hope this helps.

question you need to ask yourself will it stop the threat?

will a 22 Mag. kill a person? answer is, yes, it will. it's been proven it can kill. but if that death occurs hours or days later, what are your chances in surviving a possibly deadly encounter with someone intent on doing you harm?

why would someone handicap themselves with such a round? especially when there are much better choices.

but i suppose it is better than nothing. but, because of it's size and energy, shot placement is much more critical. can proper shot placement be guaranteed in moments of stress? maybe, maybe not.

any rimfire cartridge would not ever be my first choice if i have others to choose from.

Depends on which end of the gun I'm looking at.

In gelatin a 22 mag performs about the same as a 223. The truth be known neither round is an adequate defensive round. You have to slow the 223 down to 2,700 fps before it will penetrate to 12" or deeper. At 3,100 fps the bullet expands so quickly the 223 begins fragmenting and only penetrates around 10". I have seen a lot deer that were killed by a 223. If the shooter was at a 90 degree angle with the deer the bullet would pass through the deer. If the deer was quartering away from the hunter, which is supposed to be the best shot a hunter can take the 223 lacked the penetration to take the deer. If the 223 isn't capable of killing a 160 lb deer how is it supposed to stop a 250 lb man? The military makes the 223 work by using FMJ ammo.

This deer was shot with a 7.62x54r 180gr sp. The 7.62x54r would do the same or worse to a human. The 7.62x54r is comparable to a 308. The 180gr sp has a velocity of 2625 fps with 2750 ft lb of energy. This is the exit wound of a 7.62x54r 180gr sp.

Shall we talk again about your deer, Deer?

The 22 mag is notably more reliable than 22lr. In a carbine like the new CMR30 from Kel Tec it would be a formidable weapon with the right loads. I would choose JSP loads in 40 grain or Federal Game Shock 50 grain HP. I would not choose 40 grain HP or any of the 30 grain loads.
I know this is about rifles but a comment on the 22 mag in pistols. It does not perform well in short barrels. A 6" barrel will give you about the same power level as a 22lr in a rifle. The snub nosed revolvers are a waste of money. The velocity differential is less than 100 fps over a 22lr.

I would not hesitate to carry the PMR. It has been reliable. 30 rounds of 22 Magnum nonstop is good enough for this poster's self defense.

Should it be taken seriously? Well yes if it was coming my way I would be just as leery of it as if it was anything else.

It wouldn't however be my FIRST choice unless of course it's a zombie apocalypse in that case a Kel Tec CMR and a PMR to back it up would be my first choice. But in any reasonable scenario I"m going for at least a 223/5.56 and if I"m in a static location or vehicle mounted I want that 308/7.62. I will throw out the caveat that due to my disability and the fact I can't carry much if I have to go mobile if a good 22 mag with reasonable capacity magazines was available to me I"d be very tempted by it. Carrying a 1000 rounds of 223 is beyond my ability carrying a 1000 22 mag is not. Just have to remember the limitations of the round I":m using (as with ANY caliber) and use it prudently.

I have contemplated a CZ 512 in 22 Mag. Can the anti 22Mag guys tell me what a bad idea that is and save me some money? 😁
