derringer ballistics question..........

[JERRY]

i have a .22magnum derringer.

what kind of ballistics will i get with the various 40gr. loads?

ive looked on the north american web site, but their gun has the cylinder gap robbing some umph.....

anyone know where i can find info on this? i dont have a chronograph to check it myself.


thanks.

Try Gunblast.com. they have an article on the NAA Black Widow. I know it sounds strange but the author has some experiance with the HS Derringer. I used to have a double action derringer (can't think of the name of it to save me but it was chambered in 9MM Luger and I traded it:banghead: ).

Years ago I had a High Standard derringer in .22 mag. When I shot a 2x4 at about 4 feet away , the bullet bounced off and hit me in the upper thigh. Just made a red welt ( on me) and a nice dent in the wood. Velocity? Don't know ....but it wasn't enough to be of much good for anything. Accuracy? You don't want to know....

Apparently it will do 4" at 4 feet or so.

Amost word for word what mbartel posted.
Sustitute Davies for High Standard, .22lr for .22mag and arm for thigh.

You must remember...

short cases are more effiecient in shorter barrels. It is that simple. Ths is why the derringers were/are more popular in such calibers as .25 ACP,.32 S&W, .38 S&W, .380 ACP, 9 X 18, 9 X 19, .40 S&W and .45 ACP. Most of the "rimless" cartridges can't use the "automatic" extraction system employed by the diminuitive pistols.

The "original" deringer, (spelled with one r) was chambered in the black powder .41 rimfire. Anemic? Yes, yes it was. The "card-table" ranges at which the pistol was generally used, (3' -3 1/2') and the poor medical help availble at the time, could prove deadly!

You'll put your eye out!

R.I.P. south carolina highway patrolman Coates, who was killed by a single .22lr solid fired from a naa mini revolver (derringer) striking him in the armpit area, while the criminal who shot him sustained four winchester 145gr. .357 magnums to his obeese abdomin and lived.


so much for that.


now anyone care to get back to the original question?

you mean spelled with one "R".....

As usual, I can't find my notes, but once upon a time I actually chronographed several of the NAA mini revolvers, and a couple of Davis derringers. (Though neither of the Davis was in .22 Mag).

As I recall, the mini revolvers would produce right around 950 FPS. I suspect the derringer would do a little better.

Still, a long barrelled .22 LR pistol would probably match it, and a .22 LR from a rifle length barrel would probably beat it. Since the .22 Magnum bullet is usually jacketed, it would probably not expand too well from the short barrel. At least, that is my experience with both water and wet newsprint.

Definitely not the powerhouse that some people seem to think it is. Still going fast enough to be deadly, however.

exactly. with small caliber guns, penetration is what counts and should not be sacrifised to get expansion, because in sub-calibers you just cant have both........

Thanks, Jerry! I stand corrected!

I corrected my post. Deringer (spelled with one r). LOL!

My mistake! :banghead:

My 6 in brl .22 lr will drive through 2x4's with no problem

I testfired my Jennings J22 at a 2x4 with CCI Stingers, Aguila 60gr SSS, and
Winchster SuperX and all went through the 2x4, but then I had a P.O.S.
crappy Jennings not a class gun like a Hi Standard.

 

[mbartel]

Given the longer length of the .22 mag case, there was only about one inch of barrel that the bullet traveled down. Since I was using copper jacketed bullets, I would guess the bullet did not obturate fully to seal off the gases thereby resulting in a much lower velocity than if a softer lead bullet was used. I was just relating the incident the way it happened. I can't explain ballistically exactly why it happened that way.

And just so you know......I have seen some 2x4s that I could drive a 3 inch nail up to the head in 1 stroke. And others that might take 4 or 5 strokes.
Lumber includes many different grades, and densities of wood. A white pine board is quite different than one made from hickory.

IIRC the original Deringer (Henry) made not only pocket pistols but horse & dualing pistols too. All of his hide out pistols were single shot muzzleloaders bored to .44 to .45 caliber. These Philadephia made guns were very popular and so widely copied but to avoid a possible law suit the copies were spelled 'Derringer'. Remington brought out their line of single and double Derringers in .41 Remington Rimfire and was an instant hit with the "sporting life" as well as law enforcement as a hideout. Remington also made Derringers in .22 Short, & .32 rimfire. BTW it was a .44 Henry Deringer that ended Pres. Abe Lincoln's life.
