I'm starting to see more of that FN 5.7 brass laying on the ground at the range. If it's anything 'normal' a brass chicken will have already grabbed it... or I will. :) But 5.7 sits there for days/weeks and just rots away.

Is that because only ballers shoot 5.7 and reloading is for the poors, or does 5.7 not reload well (split necks?) or something else?

A buddy of mine had one for a while at the time there was very little load data. People had trouble reloading it. They are high pressure and some had trouble with pressure spikes for certain powders. I beleive "true blue" is the powder of choice. The cases require a lot of prep and they only last a few reloadings. Max is like 5-7 before the case splits. Less if you don't trim and prep it properly. So it is a combination of a lot of factors. At the time I was new to reloading and there was no way I was going down that road. Another mutual friend who reloaded everything and had been doing it for 20+ years also passed.
 
I believe that the brass must be coated to feed properly, so not really easily reloaded. I would take some for swaging though if anyone finds a bunch.
 
I have a reloading friend that has a PS90, and he does not bother reloading for it.

The story I've heard is that the special coating on the brass is to help it feed properly in the PS90, and normal tumbling will slowly remove that coating and cause feed problems. I've heard that some guys reload it for the handgun, though, without those problems.

Yep, plus it is a real PITA to reload from what I've heard and in the end you really haven't saved but about 2 cents per round.

The factory ammo, even when you can catch it on sale, isn't cheap. But I have not priced the bullets for this round, I have to imagine they aren't cheap. This might be a round like 7.62x39, you simply can't load it as cheap as what you can buy from the factory.
 
I have a PS90 and an AR57. I don’t shoot either in much volume, but do try to collect the brass when I’m don’t. I got the 2-piece die set for $10 when I stumbled across it, just in case I ever decided to try it.

If anybody picks brass up at the range, I’ll take it if you’re giving it away. :D

Is the AR57 the same mags as the PS90?

Yep. Topload and spits them out the magwell.

You can have the ultimate drive-by AR. Take a 40rd PMag, remove the spring and follower, and catch all 50 pieces of brass. :D

Mine is currently on a braced lower. 6” with Form 1 can tucked inside the rail. Keep two mags with it when I have it in the truck. 151 rounds including the one in the chamber.

So very high velocity round through a can, is it hearing safe?

I think so, but I never shoot without at least plugs in.

I don’t like it with a rimfire can rated for 5.7, like a Sparrow or Spectre. I have a custom 1.25”x6.5” can on the AR57 (max OD that will fit inside the rail...and it’s a monolithic upper so you can’t swap to a different one). And I run a real rifle can on my PS90. If you ever want to shoot one/both of them, let me know.

@patina @Diverdad @LeeMajors and @S&WNewb have all shot one or the other of mine

Where did you find the pistol upper?

This looks to be a wonderful round. In my sick twisted mind, if you can reload a 5.56 you can reload this round. I am one of the Poors
 
This is why I never messed with it for my previously owned PS90, FN5.7 and AR57 upper. Not worth the effort. Still have a butt load of factory ammo left over.

Just glanced over that with the release of the Ruger 57. Yea, I'm going to pass. With this info, I see why that brass is still laying there.
 
The 5.7 presents some obstacles not inherent with other rounds. Unlike the more common pistol rounds, the 5.7 is bottle knecked. Additionally, it takes such a small charge of power, that there is less tolerable variation in the charges. Furthermore, components are not as plentiful as they are with other calibers. That said, I don't own a 5.7, but I pick up 5.7 brass that I find as I think it is a curious round and may add a 5.7 to my collection in the future. I like working through and overcoming reloading challenges.
