Thinking I may break down and finally get something in 9mm

[SA Friday]

Just curious here - but I've read that the 10mm round is pretty damn hot, and can be a lot more effective than the 9mm, .40, or .45. I've never fired a 10mm, and was just curious if they're actually that potent? I'm a 1911 guy, FWIW, and doesn't somebody make a 1911 in 10MM? I've picked up a lot of 10mm brass, and it sure looks impressive.

go back a page and read the stuff on the links about the FBI and Miami shoot-out. The 10mm is a really stout round, about 41 mag stout. The 40 S&W is nothing more than a shortened 10mm round and less powder.

Most of the 1911 frames in 10mm get beat up fast. The one 10mm that seems to be able to take a high round count and still go is the Glock 20.

As for stopping power, yep, it's definately gonna stop them, but you better hold on when you pull the trigger.

I wonder what the coroner reports have to say about 9mm JHP's or HP's.

There are some odd facts stated in the report about all HP rounds.

They were saying that in some cases the HP rounds did not expand any more than a non HP rounds. Matter such as clothing fill the HP cavity and prevent them from expanding in some cases.

Can you reload 10mm with the same dies as .40S&W?Like .38special/.357magnum, and .44special/.44magnum?

I bet a 10mm carbine would be fun.....

10mm and 40 S&W use the same dies.

It is a stout round, but not all that unbearable.
Grip size and gun weight make a big difference.

Let me guess, this doesn't happen in .40 or .45?

Jerkmode and I might go shooting this weekend. We're thinking about shooting each other with our 9mm and coming back to post how it felt. We'll let everyone know.

I will let him post the details. You all might be suprised.

ALL Hollow Point rounds. That is also stated in the statement. It doesn't say all 9mm. It just stated all HP rounds.

I was actually asking about 9mm JHP's and HP's, buts it is interesting information anyways.

This is also stated in a FBI document.



"Increased bullet mass will increase penetration. Increased velocity will increase penetration but only until the bullet begins to deform, at which point increased velocity decreases penetration. Permanent cavity can be increased by the use of expanding bullets, and/or larger diameter bullets, which have adequate penetration.


However, in no case should selection of a bullet be made where bullet expansion is necessary to achieve desired performance.(35) Handgun bullets expand in the human target only 60-70% of the time at best. Damage to the hollow point by hitting bone, glass, or other intervening obstacles can prevent expansion. Clothing fibers can wrap the nose of the bullet in a cocoon like manner and prevent expansion. Insufficient impact velocity caused by short barrels and/or longer range will prevent expansion, as will simple manufacturing variations. Expansion must never be the basis for bullet selection, but considered a bonus when, and if, it occurs. Bullet selection should be determined based on penetration first, and the unexpanded diameter of the bullet second, as that is all the shooter can reliably expect.

It is essential to bear in mind that the single most critical factor remains penetration. While penetration up to 18 inches is preferable, a handgun bullet MUST reliably penetrate 12 inches of soft body tissue at a minimum, regardless of whether it expands or not. If the bullet does not reliably penetrate to these depths, it is not an effective bullet for law enforcement use.(36)"

Hollow points not expanding is the main (and best) reason that people tend to lean towards .45. A .45 starts out at 80% of the size that a 9mm hp hopes to be. That's reasonable.

If I ever had to carry my 9mm, I'd make sure to buy the heaviest, +p hollow point I could find.

22lr is where its at!!!


If I ever had to carry my 9mm, Ide probably just use strong words and throw rocks instead. Since 9mm just bounces off anyways.
