The most awesome .25acp.

Yep
Actual bullet diameter aside,
Diameter of .25-inch is 0.049 square-inch in cross section
Diameter of .50-inch is 0.196 square-inch in cross section
0.049 x 4 is 0.196

Question for those knowledgable in 25 ACP firearms…

I have a Beretta 950 Minx (22 Short) with a long barrel. Did Beretta ever put a long barrel on the 950 Jetfire (25ACP)?

It would be an interesting 25 ACP firearm.

First off, Jimbo, and everyone else with a .25 TPH, I really, really, really don't like you very much. I've had a bunch of the .22 version over the years; the most recent one has run 100%, subject to the limitations of the rimfire cartridge. Love to have a .25.
Over the years, carried a 950 Jetfire, when better alternatives weren't available. Had a matching .22 short version for practice. We did some amazing shooting with the little .22s.
Thirty two is as small as I'll go for reloading; Dillon doesn't even make a .25 conversion.
A late buddy compared reloading .25s to picking fly poop out of black pepper, so there's that.
That said, I load .32s, and they're fun to shoot. Same has to be true of the .25s.

But did you account for .25 acp bullets being .251 in. Dia.?

I've never even seen a picture of one so I don't think so.

Thanks for the response. I had a feeling it was along those lines. What the author freely admits pretty much invalidates the grandiose proclamations of performance percentages from an actual statistical evaluative perspective. When the entirety of the sample was 68 from a caliber that has been around for over 100 years, you really have to question how much is missing.

Well, I wouldn't call the numbers "proclamations" or solid predictors of future performance, but just percentages created from raw data. If you've got numbers why not do a little math?

The numbers can at least be compared with eachother from the same study.

Remember when you are talking about .25 you are talking about half of .50

Two .25's = .50.

Ha!

I was thinking more along the lines of a 45 grain bullet versus a 655 grain bullet.

That is why I said "actual bullet diameter aside." If we look up the bullet diameters it should be close unless the .50 caliber is like a .44 caliber in having a significantly smaller bullet size (the .44 having a .289" diameter bullet). At any rate, cross-section is just one way of looking at it.

John Browning designed for gentlemen to carry. History says 25% of people shot by it are incapacitated. Interesting stat. Is it the ultimate get off me caliber?

A caliber that achieves the goal of quickly incapacitating an attacker just 25% of the time is the "ultimate".
Surely if one has other caliber options, a larger more powerful caliber would be preferred if in a situation where lethal force is justified.
I will not bet my life on 25% odds of quickly incapacitating somebody(s) trying to kill me. How about 80% or better? I want the odds in my favor.

"Awesome" as applied to a .25 ACP pistol makes as much sense as "sexy" applied to a Mosin (see the other thread).

Agreed - but when in urgent need of a pistol or a rifle, having either one would be awesomely sexy.

I do love me some .25 ACP pocket guns. Sorta like jewelry . . .

If I get around to the typo. Meanwhile, there is actually more to it, so bullet weight, amount of powder, etc. Of course shot placement. A 22 in the right spot will beat a 45 caliber that misses--but always nice to have the caliber to make that well placed shot count even more.

I do love my Bernadelli handguns but I don't have a vest pocket.

This makes it look like your being a party pooper. Trying to drag this thread down?

Oh no; my bad, I was just replying to the statistic you posted.
Pardon my prior futile attempt at logic; carry that .25 with confidence.

Just remembered story. A buddy of mine was working for Dallas PD. They were leaving the jail and saw two cars pulled over under the I35 underpass. (Near the triple underpass for the history buffs).

4 or 5 Hispanic males were fighting and they heard a “Pop” one guy dropped, everybody else jumped in cars and fled.

Had to go down a ways, make a U Turn. Guy laying on the shoulder of commerce street. Dead as a hammer. One .25 through the femoral artery. Emptied him out like a 2 1/2” fire hose.

Thoughts on shot placement and small calibers.

Well as to the sexy comment, if we all found the same thing sexy there are groups of females that would be left out.

I think that is about as PG-13 as I can make that.
