Bingo. The "moon clips" allow the rounds without a rim (hence, rimless) that would otherwise not be properly seated to instead sit properly in the cylinder and eliminate the much greater possibility of the firing pin not hitting the primer.
 
Although this may seem impractical compared to a typical revolver (such as .357 Magnum variant or .44 Magnum variant) that can load single rimmed rounds just fine, there are two advantages that come to mind.
 
1. You effectively are always using a "speedloader", so reload times are quicker than handloading each individual cartridge.
 
2. You have the ability to utilize bullets that pretty much only go in semi-automatic firearms, such as 9x19mm Parabellum (an extremely common caliber). Yes, 9x19mm revolvers do exist.
 
Edit: I just thought of another minor benefit. When you empty the cylinder of spent casings, they'll all be together in the moon clip. This allows for easier retrieval/cleanup...especially in a hurry.

First, those are called "moon Clips".   THere are also half moon and 2 rd versions, iirc. 
 
Depends on how the chambers are cut.   If they are cut right, you could individually load the rounds, and they would headspace on the case mouth.  Reliability could suffer, as if the cases are a little too narrow, the case could move forward in the chamber and the Primer might not detonate when struck by the firing pin. 
 
My dad has an old Enfield .45 designed to use either the moon clips with .45 ACP or the special case called the .45 Auto RIm, which is the .45 ACP with a thicker than normal rim to give the same headspace control and distance to the primer  as the moon clips.   

I just received a DNC fund-raising call.
 
A part of their lengthy spiel was that they are raising money to target vulnerable seats held by white male republicans.
 
Me: So, hang on, the seats you are targeting are held by white, male republicans?
 
DNC: That's correct.
 
Me: I'm white and male.
 
DNC: ...
 
Me: Why didn't you just say "republicans?" It might surprise you, but I have no problems with white people or male people...
 
They hung up.

Well, I don't want to give up the ship just yet...

This election cycle has me questioning my faith in my countrymen.  
 
I thought Romney was such a lousy candidate that for the second time in my life, I voted for a Non Republican for President.  The first time got me Clinton.    Despite the rantings of the Right wing, Obama has not been all that bad, at least he has not managed to get a new gun ban passed...
 
Every election I think "They have to come up with better candidates next time!"  But at least on the Republican side, they seem to get worse...   
 
I personally distrust Hillary.   I do not trust her as far as I could throw her.   But I do not trust Trump as far as I could throw the Entire Republican field from the early part of this campaign.  
 
I weep for the future.

Here is the Smith and Wesson Model 610.
 

 
Though it is primarily chambered for 10mm Auto, it can also fire .40 S&W rounds (in much the same way .357 Magnum revolvers can handle .38 Special).
 
If you couldn't tell, I am a fan of revolvers that fire rimless cartridges.

Interesting take on the dangers of 'concept creep'

I've noticed that people say a lot of things when they're confident there's no chance of it actually happening.

Cool, I love Creed, but 'music snob' says I'm supposed to hate them now.  'Music snob' also says I'm supposed to like Radiohead and every band who is not famous yet. 

1.  Not a fan of Nickelback
 
2.  However, by a factor of 100, I am even less of a fan of 'music snobs'. 

I like some Nickelback songs. Never understood the hate.

It should be legal to punch these people in the face. With a fist.

Good Luck Nolgroth.  
 
 
Anybody know why the IRS now wants State Drivers license information?   not "required"  supposedly...

As it becomes less and less likely that Trump will reach 1237, we're starting to hear more about the truly Byzantine rules of the GOP convention.* The latest is that the eventual nominee must have won at least eight states--a condition which only Trump has met so far. I'm unclear as to how many states Cruz has won, but he's definitely not up to eight yet, and I'm not sure if he's likely to win any of the remaining contests.
 
* Seriously these guys make the rules to Star Fleet Battles look like pickup sticks by comparison.

Cats and dogs live together in millions of households in the United States alone, so the end times have been upon us for decades. In a way, the end times have always been upon us -- the climactic battle just keeps getting delayed again and again.
