10mm .vs. 357 mangums?
Which 10mm load? Which .357 load? Barrel lengths??? Action types?
You want devastation on the BG? Then go to 12 gauge.
Otherwise pick the one you can shoot best and don't sweat over it.

I keep 'em handy. Maybe I'll have time, maybe I won't, but if I do, my eardrums will thank me.
FWIW, I do keep a G20 as my primary HD handgun. Not because of the noise, though: 16 rounds > 6 rounds.

MachIVShooter you say I'm incorrect when I say:
The 10mm can have potentially more penetration than a .357 Magnum, so I'm going to assume you believe the reverse to be true. According to Hodgdon a 10mm pushing a 135 gr. bullet will travel 1476 feet per second while a .357 will travel 1314 feet per second. On the other hand the (again according to Hodgdon) a .357 magnum will push a 180 gr. bullet at a maximum of 1422 ft/s, 135 ft/s faster than a 10mm. So like I said, "Depending on the weight of the bullet and how heavily either round is loaded, the 10mm potentially can have more penetration." So no, I'm not incorrect.
You also claim that I'm incorrect when I say a 10mm has a flatter trajectory at longer distances. According to ChuckHawks http://www.chuckhawks.com/handgun_trajectory_table.htm they're very nearly identical, so according to this table I was in fact incorrect.
You say, "FACT: No cartridge is inherently accurate or inaccurate." That's a rather bold statement, especially if you consider that there are target loads on the market for a reason, as well as a reason why professional shooters reload their own target loads. Cartridges may not be inherently inaccurate but there are definitely some out there that are inherently MORE accurate.

It's late and I'm too tired to do a comparison and at this point I really don't care anymore so I'm just going to go ahead and say you're right, just for giggles.

Mack vs Freightliner!! Enough said. Stupid thread. Why do people keep asking these questions? If its not 10/357, its 12g/20. Why not AR vs AK? Why not 40 vs 9 or 45.
Enough already!

Demitrios,
I'm not going to sit here and argue with you ad nauseum when the facts are readily and widely available if you'd just broaden your search. Looking at one or two loading manuals and making these determinations will lead you to false conclusions. For starters, no manual that I'm aware of shows real top end loads for either cartridge, but there are safe loads well above what's published by Sierra, Hodgdon, Speer, Lyman, etc.
The 10mm cannot push a 135 faster than the .357 can a 110 or 125. Additionally, these are not the bullets we choose for penetration. Quite the opposite. Penetration is acheived with the heaviest and hardest bullets with the highest sectional density. I've already told you what those are. Thinking that the fastest load in a given cartridge is going to have the best penetration is a belief you need to dispel, for it is grievously wrong.
On trajectory: Because the .357 magnum is able to push lighter bullets of higher SD and BC to higher velocity, it will have a flatter trajectory accross the board with top loads. There is nothing to debate here.
No. Accuracy is a function of the gun, and using a load that agrees with that gun. It is completely independent of the cartridge. Some have earned a reputation for better or worse accuracy because of the platforms they're most often chambered in, but the reputations are false. There's a long list of variables that contribute to or detract from accuracy, but the cartridge case is not one of them.
Giggling or not, the 10mm Auto and .357 Magnum are ballistic twins, with the .41 mag a good bit above them.

They are about even in the full size category, so how do they stack up when you put a glock 29 against a 2.5 inch magnum?

Yes! Another cartridge comparison thread!
10mm is the only handgun cartridge capable of blowing a man clean out of his sneakers in a shower of sparks.
Here's proof:
If Inspector Callahan were around today, he would be packin' a 10mm

When swamp fox ammo was around his max load sold for the .357 was a 125gr shot at 1900fps/1000lbs of energy the 10mm never made it this fast or as much energy but I would be happy with either.

It didn't do that out of 4-6" guns. His claim was with a 5", but I've never heard of anyone actually getting those results on a chronograph. Buffalo Bore's top .357 load is a full 200 FPS slower than the Swampfox claim, and they're not exactly known for weeny loads.

the 10mm vs. .357 debate really is a platform one. They both have great handload potentials, both are under utilized when it comes to factory ammo.
10mm is generally an auto pistol load, the .357 a revolver load. Choose the platform you are comfortable with for the job you want done. That will dictate your choice between the two rounds.
IMO.

both will cause extreme pain and soiled undies
The OP has logged more "vs" threads than anyone in the history of gun forums. However, the threads are usually a bit more creative than this kind of caliber war fodder...
As for the 10mm vs .357, they both suck, get a .45
There, someone had to say it.

I'm a big time reloader (thousands and thousands of rounds) and 10mm brass is not cheap. I had a 10mm Smith model 1006 that was not cheap to shoot due to the fact of loosing the brass. Too much time on all fours when I could have been shooting 
. With a 357 you shoot and just dump the empties in your bag . Now for a cheapskate reloader like me there is no debate...357 hands down!!!

With the new handguns available round count isn't as much a factor. Many complain 5 rounds or even 6 rounds are not enough but one of the most carried handguns of all time is the 1911 which carries only 7 rounds. S&W makes a the Model 327 which has a 2" barrel, weighs only 21.4oz and carries 8 rounds of .357 Magnum goodness... Granted, it's larger than a J frame but it has to be to carry 8 rounds. Sorry but if you can't get it done with 8 rounds of .357 Magnum get an AR15 or call the SWAT team!
I'm just sayin...

Own a .357 compact, and a .45 ultra carry, love them both. Think I want my 40 more now than ever, it is the complete package.

if you can find some of the original norma 10mm loads, go with the 10mm, otherwise they are both equally proven man stoppers in the same platform.
The original norma loads were much hotter then anything you will find today with the possible exception of the buffalo bore company. even the winchester silvertip 175gr loads were downloaded in recent years...

The reason I posted this thread was because I saw a few youtube clips that purported to reflect 10mm superior to the 357 magnum.
In 357 platform for me is a revolver. 4 to 6 inch barrel. I have a variety of them King Cobras, Pythons, 686 etc, but as far as 10mm is concerned the platform will be Colt Delta Elite.
I have DE in 357 but I don't take it as a SD or HD gun. Its more of a novelty for me to shoot sometimes and that's about it. This is because of its size.

A 10mm and a 357mag might expand but a 45 can't shrink!
