>A little bigger than 9mm
>Almost same pen as 5.56
Someone should do a small revolver that holds 5 bullets, I bet it would sell fast.
How come this didn't get cheap yet?

Because it’s shit
Because frick ya mudda
You can get the fn stuff for <50 CPR during sales. It used to be way more than 2x 9mm. With the caliber becoming immensely more popular in the last couple of years supply will follow.
>Almost same pen as 5.56
Delusional.
relative to all the 10.5/12.7 homosexual shit people build nowadays
Because the case is designed to feed from a perpendicular 50rd magazine and then rotate 90 degrees to feed it cannot have any taper. So this is a straight-walled case that also cannot have a large protruding rim. In order to have adequate extraction, the casings are coated with a dry polymer lubricant as part of the manufacturing process which is unique to it and requires specialized tooling. Even setting aside potential patent issues (which would no longer be an issue since any such patent would have expired by now) this requires specialized ammunition production with special tooling which is a considerable investment.
With a gradual feedback loop of more manufacturers producing firearms in 5.7x28mm on one hand and creating more demand/supply of the ammo from a wider variety of ammo manufacturers on the other, this is actually taking place. It just couldn't take place overnight since the up-front costs were considerable and the market previously too niche.
5.7mm hasn't gotten "cheap" yet, and probably will never be as cheap as 9mm or .22LR due to the required coating (and consequently not being reloadable) but it has gotten cheaper and more available than it ever has been.
>5-shot 5.7mm revolver.
That may be difficult due to the inherent difficulty that revolvers have in extracting non-rimmed cartridges. They also like to not play nice with necked ammunition. Revolvers in .22WMR seem like a more natural solution, along with the possibility of being downwards compatible to far cheaper .22LR given a conversion cylinder.
The coating is largely only necessary for the p90. Afaik several of the handguns run fine without it. Nickel plating would also provide the requisite lubricity in addition to being reloadable.
thx, good info 🙂

AFAIK? but is anyone running Full House loads in handguns without special lubbed casings?
Ain't these supposed to be higher PSI, so might have issues that 9mm etc don't?
S&W claims the m&p doesn't require laquer at all. I've also heard that unlaquered batches of brass have worked fine in the Ruger 57 and FN Five-seven. I'm extrapolating to the PSA. From what I read, the biggest impact is in feeding from the P90 magazines and in extraction in the P90. Full power loads are extremely expensive at the moment and they invariably come laquered, so jury is still out. It isn't insurmountable by any means though.
It is due to the shape of the cartridge. Most handgun cartridges have a slight taper to help them unstick from the chamber on extraction, or in the case of revolvers a rim that allows for easier extraction. Doing so introduces a curve to any magazine you stack them up in, which is a no-go with the P90.
That may be an option, but if you market a loading of the ammunition designed for the P90 that is not suitable for use in the P90 or PS90 that fact is going to make people reluctant to buy it. They may intend to use it in one of the many other firearms that fire the cartridge, but a potential customer would see it as inherently inferior.
You are also going to get frequent claims from people who try to use it in a PS90 and encounter problems no matter how clear you try to warn them that the ammunition is not suitable for that particular weapon.
I don't see big manufacturers skipping on laquer, but I could definitely see it becoming common for reloaders and smaller companies working with virgin brass. Buffalo bore, for instance, very frequently puts out loads that only work with certain guns, so I could see a world where the put out some kind of "Heavy 5.7" intended for handguns that is designed without any regard for the legacy 5.7 guns. To be fair, not many people have a PS90 either.
I can see that. There is a community for people who roll their own 5.7mm and I'm sure they would love a source of virgin brass to play with.
>small revolver that holds 5 bullets
Why only 5? It's a 22cal round with a .307" rim size. You could fit 7 or 8 in a small revolver cylinder.
>revolver
this caliber is dependent on pressure
>how come this didn't get cheap yet
It's less than a third what it was like 2 years ago. It's the cheapest it's ever been.
>almost same pen as 5.56
As a 5.7 gay: lolno. Saying shit like this is as moronic as the people saying it's the same thing as .22mag. Just straight up not true. Terminal effects are comparable to 9mm with slightly better penetration, less recoil and higher capacity, and that's all it ever needed to so.
It's a nasty little fricker out of a 10.5" barrel but there's no need to make shit up lol.

Dumb Black person
What is it about necked cartridges that makes it prohibitively difficult to make a revolver?

there's boomer fuddlore about bottlenecked cartridges elongating in the chamber and tying up the cylinder, but really the only issue is that there's more surface area for the brass to potentially stick to and since revolvers are generally used to shoot powerful and high pressure cartridges the chances of it sticking tend to be higher.
the lack of rim and lack of taper and it being a very high pressure cartridge mean that 5.7 would probably be an enormously shitty cartridge to use in a revolver even if you can just headspace on the mouth of the cartridge
Locally it's about 35cpr. It is cheap and it's getting cheaper by the day.

Bottleneck cartridges in a revolver is a moronic idea and you should feel bad for suggesting it.
It's a trash handgun round, inferior to 9mm, and expensive PCCs aren't very popular even if they're neat. It's done ok by new small cartridge standards, not like its 100cpr+ unobtanium, but it's never going to be that popular so it will always be more expensive as long as mass manufacturing matters.
It's a lot cheaper than when I first bought my ps90, but still fairly expensive for what it is. Regardless though I like it. Fun to shoot and effective enough out of 10+ inch barrels, pistols are 50/50 though.
Because it's not commonly used?
The cheapest ammo is stuff that is widely adopted by police and the military.
