whats wrong with 10mm?

Many of the early problems after the FBI adoption had more to do with using a standard .45ACP recoil spring that tarnished the gun's reputation.
The .45ACP spring is not enough for the 10mm Auto, and so it let the slide slam back and forth like a pendulum. This both battered the gun and increased felt recoil and muzzle rise.
Rather than fix the recoil spring they downloaded the round to work with the recoil spring. By the time the recoil spring was fixed the FBI lite load had already been born. Then someone saw the cartridge was being loaded so lite that much of the cartridge space was being wasted. So they made a shorter round that could function in 9mm frames.
The gun manufacturer$ loved the idea becau$e in$tead of having to make new frame$ for the longer 10mm $et to dominate the market they could just use existing 9mm frame$$$ and direct the market in that direction.
The .40$&W was born.


So the reason the 10mm auto fell from power was a combination of poor factors that shouldn't have been.
Had the delta elites came with the proper recoil spring from the state the FBI lite would likely have never been created, and the .40S&W never created based on that weak loading.

Please provide a cite for this post. It is controverted by all the information I have read on the development of the 10mm and it's adoption and subsequent abandonment by the FBI

The recoil spring was not the reason the FBI downloaded the 10mm. That was decided during cartridge evaluations being done at Quantico. One Colt 10mm was evaluated, but the model is not mentioned.I don't even know if it was even in production at the time the FBI was looking at the 10mm. The FBI tests started the same year the Delta was released. (1987-88) The S & W 1076 autos started having reliability issues and Smith went to Winchester for a cartridge with FBI lite ballistics that would fit in a 9 mm frame. I have never seen any information that the recoil spring had anything to do with any of the FBI evaluations.

I've been doing informal tests on handgun rounds for many years and of the auto cartridges the 10 mm expands better than the rest especially with 155 grain hot loads. It might be too penetrative for sd against people, but against things like hogs, it is very good. A 44 mag or bigger is better, but not as controlable. I carry a Glock 19 anyway so to switch to the 20sf is easy.
 
I have 3 610's no dash number. 2 6.5 inch barrels with fluted cylinders and a 5 inch safe queen. Also a Dan Wesson Pointman 7, and a 1086. I LOVE my 10mm.

If I had that 5" Model 610, I'd love it too! I really want one of those. (smile)

PS: OK, I'd really love to have that Dan Wesson 10mm too!

The 10mm is a very inaccurate round simply because it is not a compressed load. The 40 S&W is the 10mm compressed and it is much more accurate and available. Bren 10 is gone.....get over it! DO NOT waist your money on a 10mm.........................they are over!!!!!!!!!!!!

Nothing that a stiff shot of testosterone won't cure ... :rolleyes:

One thing wrong with 10mm is that 40SW can be loaded hotter, launched from an identical platform with full case head support. At the high pressures these cartridges operate in, the LPP will blow out before you realize the case-capacity or web thickness advantages of the 10mm. Or so I've heard from the world's most interesting reloader.

Joker 19, I'm wondering what experience you have with the 10mm. I have two guns that will outshoot yours. :D One is Glock, and the other is a Caspian Government Model, built by SDM Fabricating (Scott Mulkerin). I'm sure there are other 10mm owners on here that will also "put up". Why would you think a cartridge is inherently inaccurate? Compressed, or slightly compressed used to be an issue with blackpowder, but that ship sailed a long time ago. Is one inch at 25 yards accurate enough, or 1.5"? What .40's are you shooting, and what do they deliver?

Seems a useless round to me. For a self defense scenario it isn't going to do anything that a 9mm/.45 can't do. If I need more horsepower than that, I need a long gun

If I'm going to bear country and I'm worried about running into a big bear, I'd rather bring a .44 Mag (if I can't bring a long gun)
 
What's wrong with 10mm?

Compared to .40 S&W, 10mm:

--has a longer OAL, and so requires a larger-gripped pistol
--is more expensive
--is often harder to find
--has fewer pistol models available
--has little ballistic advantage for bullet weights 155gr and below
--has significant ballistic advantages for BWs 180-230gr, but that may not matter much for SD use against human attackers
--has more recoil at maximal loadings for any given bullet weight
--has a mythology around the Harold Fish case
--was eventually given a not-such-a-great-idea-after-all assessment by its conceiver, Col. Jeff Cooper.

That's about it. (For a longer list, start a thread entitled, "What's RIGHT with 10mm?" :cool::p)
 
For me what is wrong with the 10mm was: Grip size (G20), ammunition cost and ammunition availability.

That's why I sold it.

It was also too big to properly carry concealed and even though I kind of put that use off at the time of purchase I ended up realizing that I would much rather have something I could readily conceal. I'm very happy with the G19 I purchased in its place (this was 2 years ago).
 
I am here at the store with my .44 magnum, which is laughing at your 10mm girly rounds.

j/k

44 magnum defense rounds are cheaper and easier to find for a gun that is ... cheaper and easier to find ... and If I chose to reload ... it will be cheaper and easier to find.
 
I would love a 10mm, but only in something 5" or so and steel. That Delta Elite and the DW are still in production or a Smith 10xx. I've heard mixed reviews on Witness 10mm's and a buddy of mine has a Glock 10mm. I think it's true potential lies in the sub-machine gun market or pistol caliber AR's. That's what I'd like to see one in. A 10mm AR that accepts Glock magazines and then get Glock to make 22 round magazines for it. I don't think any other pistol caliber carbine would last long compared to it.

Well ,for starters, it delivers WAY more pentration than both, and brings with it WAY more energy and potential destruction. You can never have TOO much, when defending yourself, right? :D

Except for this ...yep useless

I shoot .40 S&W, not 10mm, for the same reason that I'd shoot .44 special and not .44 magnum, or .38 special instead of .357 magnum. Overkill, for me.
 
Nothing is wrong with 10mm, it is in my opinion one of the best all round cartidges that you can shoot. Guns are available from Kimber,Glock Tanfoglio, Colt and a few others , I personaly own 11 ,10m weapoons including a S&W 610 revolver from 1999. AS long as you hand load ammo is affordable and available. performance is #1, compared to about most everything else.
 
Useless. To be without use. I know exactly what it means. Now, feel free to show me where 10mm would be of use to me

1. For CCH I carry a .45
2. For range practice, I shoot cheap .22LR ammo
3. For plinking, I shoot .22LR and/or 9mm (for cheaper "service caliber" practice)
4. I do not handload, nor do I intend to
5. I do not live in bear country, nor do I travel through the woods
6. For HD, SHTF, etc, I have long guns to grab
7. My hands prefer a midsize gun (Glock 19 size is perfect for me)

So again I ask, what can 10mm do for me that a .45 cannot? Is .45 an ineffective man-stopper? Does .45 not penetrate enough to strike vital organs in a human attacker? Why do I need to be able to shoot through a car door with a pistol? If I need more power than my CCH .45 and I can make it to my truck/safe, would a 10mm pistol be a better, more powerful choice than grabbing a rifle/shotgun?
 
So again I ask, what can 10mm do for me that a .45 cannot?

Send a 230 gr bullet down range at 1120fps with 641 ft./lbs.from a 4.6" Glock 20.......and carry 16 rds in that package. Or, shoot loads from 125gr. to 230gr.
And for the record, I love both........
