Found it.
The Hornet cartridge for the Savage 10/11/12/16 rifle.
5.7 x 28mm FN
Looks like a miniature 221 Fireball.
Case length is 1.135 inches. COAL is 1.525 inches.
Holds about 7.5 grains of powder.
From a pistol barrel (4-3/4 inch) gives about 1,700 fps with a 40-grain bullet.
From a rifle barrel ought to get above 2,000 fps.

VERY COOL!!
There was a guy here on the forum trying to do this with a wildcat not too long ago......
I'll have to do some research on it.
One of our local FFLs just bought one for her CCW. I didn't understand why she wanted that particular cartridge for defensive use but it's her choice.
I never thought about chambering a rifle in that.
The 5.7x28 is a very neat little round and not as costly as one would think. They seem to be very accurate given the FiveseveN (what FN calls the pistol) is accurate to 100 yards with open sights. The actual groups sizes were surprising. The round is very fast for it's size. I know several people that have it in T/C handguns and love it. It should do well for what you want and a box of 50 rounds runs $20, not bad.
I have looked at the spent rounds and thought what a cool .20 or 17 wildcat it would make
Been kicking the 5.7x28 around for a while now?? Have a few hundred peices if range brass and finding more all the time. Would necking it down to 17 would make it a reloadable 17HMR?
Found another neat use for the little case too, gotta read down the page a little till you get to pics. http://www.longrangehunting.com/foru...er-hunt-47581/
Bet it'd work real good in a 20 inch barrel.
Best I can tell, the case rim diameter is .307. Does some one make a bolt head for it?
Some one needs to build a .20 or .17 Wild Cat based on it. CRRRRRAAACKKKK!!! I bet it would be an awsome almost 200yd. varm cartridge.
HAHA. . . I know someone who has already been pondering this for close to a year, and he is the one to build one too. . ..
Where can you find ammo?
Not sure about general availability of this ammo, but a local dealer tells me he has sold half-dozen guns chambered for this round just this month.
.
The place I work part time always has stacks of it and it moves quickly
Pickt up a box of 5.7x28 ammo and I aint even got a gun to shoot it in ::) Was checking to see what it would work in hoping it might work in a 93 17HMR action, it would fit the magazine for size but not length :-\ Next I tryed it in a single shot Savage, its too small and will not ramp into the chamber :'( Tryed the little CZ next and if a guy bushed the bolt and redid the mag a little it might just work 8)
The easiest solution might be to rechamber a 17HMR TC ancore barrel? Would make a great little carry gun but dang I hate breaking the sight pickture to reload!

I picked up a spent shell at the range the other day and matched it to a 20 VT. Wow for a center fire it sure is small. Since it was only a shell I have no idea what the bullet would weigh. It looks like it COULD be a real fun cartridge to work with and one pound of powder should go a looooong way. Does anyone have any load data?
The Lyman 49th Reloading Manual has loads for 35, 40, and 45 grain bullets.
The powder charges range from 4.3 to 7.5 grains of powder.
Velocities from a 4-3/4 pistol barrel range from 1400 to 1800 fps.

20 rounds in a pistol is always a great thing. The recoil is minimal also which is good for most women shooters.Quote:

In a rifle I think it would be neat but there are a few other loadings that would work just as good. Now if you had a Five Seven pistol and a PS90 (or even better, a P90) then having a bolt gun in the round would make all kinds of sense. I believe in having ammunition commonality among all my firearms and right now I have 223, 9mm, recently added 45ACP and of course 22lr.

I too believe in having multiple rifles or handguns in each cartridge.

Ok...it's available, but where can I get some ammo? I have to have some!
Thank you Hammer. Santa has the 49th in his bag I hope. Now all I have to do is find a bolt head that it will work with. Fred are you listening?

Fred, I think you need to make a .20 or .17 wildcat out of this round. I wonder what it would do with a 32gr. .20 cal tip or a 24gr. .17 cal tip!
The wildcatting part will be easy. I'm gonna start with some ammo and a magazine from a Five-Seven pistol and build a rifle around it.
A problem I have had with the shorter cases is that they fall off the bolt face before ejecting. That is as soon as the case exits the chamber it "ejects" off the bolt face and falls inside the receiver between the lugs and breech face. What I did to fix it was disable the ejector as a temporary fix. Next step is to machine through the receiver on the right side up to the breech face so the round can ejector normally. This will be on a permanent 45 ACP build or maybe I just rechamber for 450 Bushmaster and not worry about it.
Hopefully the 5.7x28 is long enough to eject correctly.

I have always been interested in this little cartridge, as well as the 5.45x39. Would be interested in knowing how the bolt gun works out.
My plan is to build an action specifically sized for that cartridge.
I wonder if one of the new 22 Hornet/221 Fireball/223 Remington actions would be easier to adapt. I was looking for a used and abused one for a 7.62x25 Tokarev build. It seemed like it would have been a perfect fit for my project because the Tokarev rounds I was loading were 1.75" long when using the heavier bullets at subsonic levels.
Unfortunately those actions are still relatively new so there were any that were available cheap.

I'm looking at something the size of a CZ 527 American. You need the smaller diameter bolt to keep the cases on the bolt face till they flip out the port.
I did the Mil x .03937 and came up with .224, so the 5.7 is a 22 on steroids . . ? Right? I have a .17 Rem Fireball, and for these old fingers - that is about as small a caritridge as I think I want to try to reload. Can you imigine that small a cartridge and holding the bullets and getting the powder into it, when there are better cartridges out there that will do nearly the same thing. I guess boys will be boys and we just have to play don't we . . ;D ;D ;D ;D
The 5.7x28 has virtually the same velocity and energy as a 22 magnum when comparing the same bullet weights. A 32 grain is 2350 fps and a 40 grain is 1950 fps in the 5.7x28. A 40 grain is 1910 fps in the 22 magnum.Quote:

Can a Savage bolt head be retrofitted to use this little guy?

How about the "mini mauser" action that savage has always needed in its line up
