    I think the 5.7x28 would be a great round for coyotes and liked size critters.
    Yes I know that a .22hornet is better suited for the job and has more factory loaded ammo. I'm Just surprised no one is making a bolt gun in 5.7

    I'm surprised that CZ hasn't turned out a mini-Mauser in that chambering.

    It should be easier to reload than .22 Hornet, the cases should last longer and you can often pick up the brass for free at the shooting range.

    Much more economical than the Hornet. It has a smaller case but operates at higher pressure, so ballistics should be somewhere in the same ball-park.

    Hard to compare without same-length barrels to work with.

    I have heard of Contender barrels, but that's a single-shot.

    I would wait until the 5.7x28 is established as a pistol round. Everyone wants a 5.7 until they find out they can't get ammo that will penetrate a bullet proof vest. Most people want a real varmint rifle in a varmint caliber. The 5.7 would be a fair varmint cartridge but pretty lame compared to more versatile caliber like a 243 or a 25/06.

    I read about reloading the 5.7 X 28 cartridge few years ago .They use the same bullets as used in the 22 Hornet but had a smaller powder case capacity with a higher psi and fired the ammo in a semi auto hand gun. Should the cartridge be fired in a rifle barrel of the length as a Hornet the bullet velocity would some what less but some what more than a bullet fired from a 22 WMR rifle. It would be a pour choice for shooting coyotes at any distance. But it would be an interesting round for shooting prairie dog pups in the spring when there are a lot of shots within 150 yards. A 17 HMR rim fire would be just as good and one would have not have to take the time to reload the center fire ammo. It was news to me that the Savage model 25 rifle had ben chambered for the 5.7X 28 MM round. Might be fun to try one. Savage may longer be chambering their model 25 for the 5.7 cartridge.

    most rifle cartridges will penetrate a bullet proof vest with out being armor piercing. and BTW armor piercing ammo in pistol calibers is illegal IIRC. so why would someone be looking for something they can't legally own anyways?

    please refer to the ATF site, Title 18, USC, Chapter 44, Public Law 103-322.

    it will explain the illegalities of armor piercing ammo in pistol calibers.

    The 5.7 cartridge is not listed on the Savage web site as one now chambered for the Savage Mdl 25 rifle. One can get a excellent Remington 221 Fireball rifle which produces more bullet energy than the 5.7 or 22 Hornet rifle. The Fireball has little recoil and muzzle blast.

    Probably the same reason why bolt actions are not normally offered in 7.62x25 or 357 SIG - it offers no particular advantage in this type of firearm.

    Why not use a 223?? Same bullet waaaaaay better ballistics. Most .224 bullets perform horribly at the very low velocity of the 5.7x28. They need the speed to be effective.

    Most 22wmr rounds outperform to 5.7x28. You don't get much of a boost from a longer barrel on the 5.7 because it uses pistol powder. I suppppppose you could use rifle powder but then you lack case capacity.

    The 5.7 like 40sw is a an answer still on the hunt for a problem.

    I think the point was to pack 20+1 high velocity rounds in a service pistol.

    Why not just go +p with a big CZ or 92FS; they have mags that big?

    How much more force does it really get you comparatively?

    Those are extension mags. FN apparently wanted to limit the grip size, but provide enough bullet velocity to penetrate light armor. It is true a hot 9mm will do the same at least. There was a recent article (Shotgun News?) - all Russian military 9mm ammo is armor piercing.

    http://www.cz-usa.com/products/view/P-09Duty/ OK, 19 round mag and not in the cz-75b.


    Makes sense, their .380acp/9mmMak has always had a reputation as being hotter than our .380acp.


    I still think the 7.62x25 could have served the same purpose with a more modern projectile. I keep my cz-52 ready, just in case armored ninjas attack.

    I had herd about the savage but when I looked on there website seen nothing on it. Like I said l know there are much better choices that would be more practical. I just think it would be a neat and fun varmint gun.

    I run 20 round mecgars in my m9a1. Gives me 21 before a reload. Mag doesnt stick out the bottom too much

    [​IMG]

    Mecgar in the gun and the one on the right is the oem beretta 15 rounder. Replace the mecgar +2 floorplate turns it into a flush fit 18rounder. I find the flush mags a severe disadvantage on reloads as they are much harder to seat quickly.

    90-115 grainers in fmj are sufficient and well known for their ability to punch holes reallllly well. They don't need much help. I carry hornady critical defense in the gun and fmj in the spare mags.
