Went to the range with my buddy to shoot his FN 5.7x28mm one and my 460 WBY.

Well I came home with my 460 WBY and His (now mine) 5.7x28mm. I love this gun!

Fotis, glad you like it, but I just can't warm up to plastic...

Fotis, excuse my ignorance but what caliber in U.S would that be comparable to?

Long

The 5.7X28...


Travis

That is a cool pistol Fotis. I want one myself.

I was talking to some guys the other day and they said the round isn't as difficult to reload as the press have made it out to be. Made me REALLY want one.


Travis

Very nice. Congrats.

linky

I just got my dies today. I will load tonite after work....

Bad azz! Let us know!


Travis

I will be loading 45 gr Sierra SP 40 gr BT's and 50 gr BT's.

I'm jealous. What powders and primers you going with?


Travis

I found this very interesting. See it all the way through to see the 5.7 and the 45 ACP.

I'm not looking to start a flame war here, but the 5.7x28mm cartridge test video posted above didn't really impress me.

Penetration was suspect (only 10.5" on the non-denim test), and the bullets fragmented rather badly. The recovered bullets weren't weighed or measured for expansion, but the fragments displayed near the end of the video clearly showed bullet integrity was less than optimal.

If this ammunition performed this way at the labs in Quantico, it would not be approved or recommended for LE use and I'd be hesitant to recommend it for personal carry/defense.

FWIW, the test protocol used was not exactly kosher. The denim should be NEW denim, and all four layers should be vertically oriented and in contact with the gelatin block. The gelatin block should be at or near 4 degrees Celsius; the video doesn't show a thermometer, so we don't know what temp these tests were run at (gelatin's resistance and elasticity properties change significantly as it warms).

A minimum of 10 shots into calibrated gelatin should be done to assess ammunition/bullet performance. Showing a video of one or two shots is entertainment, not science. Not that entertainment isn't good, but don't look at this video as proof of anything about this ammunition, good or bad.

Finally, modelling clay is essentially useless as a ballistic test medium. Stick with the gelatin tests if you want to know how ammunition is going to perform in flesh.

I see your point Doc. However there has got to be a 22 cal bullet that will work better out there. Maybe a 50 or 55 grain that expands and penetrates more than the 12" minimum?
Kinda new to this 5.7 thing.

I'm pretty sure there's decent 5.7 ammo out there, and to tell the truth, even the stuff demo'd on the video might be good enough to run with... he just doesn't post enough evidence to say whether it's good or bad.

If you decide to carry this gun for defensive purposes, check into what kinds of ammo LE carries in their 5.7's, and carry that. It'll be a bit of a search, as few US LE agencies use this caliber, but I know the info is out there.

In the meantime, I'd carry that thing in the woods every chance you get and do some ballistic testing on squirrels, rabbits and gophers. I bet it's a dandy on small game.

relax, dfe, I'm not poopin' on anybody's caliber parade... just doing some education on the science of ballistic testing.

I can tell you the prairie dogs will be hurting here this summer.

If you can find some...we are still recovering from the plague around here...

Fotis,

You've got a great gun. I loved mine and I plan on buying another. I'm probably going to get the all black version. I have a ps90 and I love it, too. I'm a fan. The 5.7 is one of my favorite handguns ever. Have fun with it!

Gotta go west for them.....

The only ammo that availiable to civilians are the non expanding 27 gr. mono HP's and the 40 gr. Hornady V-Max loads.
I wouldn't be too nervous about using either for defensive purposes. I've run both against a .357 load that pushes a 158 gr. SWC at 940 fps. which is a minimal, but effective load.
Against a 2.5 galon rectangular water jug, the .357 load will rupture the back half and just barely penetrate out the back of the jug. The bullet can be picked up on the ground behind the jug.
Both of the 5.7 loads blow out the front half of the jug and dimple the back of the jug. That's 12 inches of penetration. The V-Max load fragments, but still raises a dimple at the back of the jug. And the front of the jug breaks up more than it does with the .357 load.
I just got my dies as well as some 40 and 45 gr. Sierra .22 Hornet soft points. Since these are designed for Hornet velocities, I want to see if they hold together and penetrate better. My load data also says I can get up to 200 fps. more than the factory V-Max load with the 40 gr. Hornet bullet, BTW. E

I'd shy away from the V-Max for social purposes myself, as it does fragment violently and doesn't penetrate gelatin or flesh very well at all. They're great on varmints, of course. I use V-Max 40's in my .223 "crow load" (not that I would shoot a protected migratory bird like the crow, of course!) and it positively vaporizes ground squirrels and such. I think your 40 and 45 gr Sierras would be very effective as well. Looking forward to hearing how they work for you.

This is the one I am currently working with

See the reviews. Seems tough enough but I have about 50 milk jugs just waiting to get assassinated!

Will also try the 50 gr BT's.

Elite ammo is using them for their protector II lineup. In the video you can see a lot of shank left after the gel exit.

Well said......

OK did some water testing for fun.
45 gr Sierra soft point (not the hornet bullet)

Load was 10 gr of LILGUN for a velocity of 1900 fps or so.

The bullet went through 5 water jugs, the 1/2" wooden backstop and bounced of my shed!

Never recovered the bullet but the impression of the bullet on the shed wood looked perfectly oblong and showed no expansion.

I will be testing the 40 gr Nosler BT and the 50 gr Nosler BT next.

This thing is a penetrator from hell!

Very cool! Glad to see that a good guy has a really awsome spacegun! Looking forward to further reports.

BTW, my PMR30 wants to be an FN5.7 when it grows up...

For now, it is this poor boys version.

Based upon how loud my PMR30 is, I am guessing that the FN5.7 is a decibel beast as well. Have you noticed such?

As soon as the water jugs thaw out!!!!

You're pontificating and condescending. Every post you make RE: the 5.7 tells us much more about you than it ever could about the cartridge. Someone so ignorant posturing as an expert would be hilarious ...if it weren't so pathetic.
