What are SS192 and SS196 valued at currently?

Anybody ran Elite S4 through the 5.7 M&P yet?

You don't. You leave the factory coating alone by cleaning it in simple green, and water ;)

I got my M&P 57 in today. My gosh the grip is horrible.

The AE TMJ may actually be fine in the M&P. I noted a nice healthy polished feedramp. I've run 7500rds of 5.7 over the last 3 yrs, and I've had less than 10 AE failures regarding the dreaded set back. That failure % is LOW. Is it under powered trash? Yep, but at least in my 11 5.7 guns doesn't seem to be an issue.

Look I don't have as much experience with the 5.7 as you guys do but, that AE can be salvaged.
If you reload, a good firm crimp can be applied with a Lee factory crimp die.
Yeah a guy shouldn't need to.
It also took the lot I have from all over a pie plate size down to 1 1\2" or so groups.

And now I have 3 of these things.

Ok. Another 200 today and three problems. All at different times. All different mags. All federal red box. The case got stuck in the chamber, live round. Gun would not go bang and I had the to hammer the slide back out of battery to eject the stuck round. Have no idea why they are sticking.

Back when I played with x25 chambered pistols, a lot of that surplus had flaired and or boffed necks.
It would feed most of the way in the chamber but not extract if one didn't go off.

Since they can't be bothered to crimp that stuff, maybe that's what's going on.
Or the case is too long in the neck.
Or the chamber is tight.

I don’t think the chamber is too tight because this has only happens a few times out of hundreds and hundreds of rounds. I’ll do a really good cleaning of it.  Especially the chamber

There was a rumor on reddit that the M&P 5.7 might actually be able to run 5.7 without the casings being coated / lacquered.

No idea if true, but that would be a positive development.

My buddies FsN MKII will only run reloads with the cases lubed, its that sensitive to coatings. And he's an extremely accomplished and experienced reloader of oddball/bottleneck cartridges.

I had 2 of these failures within 75rds.  No other ammo gave me any issues :S

just picked up an M&P57.  Now to get a red dot for it too (none of the ones I currently have "unused" fit, like the Eotech EFLX, naturally...)

I also have a decent amount of AE 5.7 on hand, and a Lee Factory Crimp die for 5.7.  I'm thinking about running the AE through the crimp die for "just a touch" of crimping so see how it works.....

the factory ammo utilizes an adhesive to (poorly) retain the bullet in the AE57 load.  My thought is that adding a light crimp will help prevent bullet setback or separation issues, but not affect chamber pressures or anything.

It's more of an issue with guns without a feed ramp specifically P90 magazine guns. The M&P has a feedramp so stoppages related to AE TMJ should be (should be) less.

Now that you mention it, yes, it has been a bigger issue in my PS90 vs. Ruger 57 pistol (likely going bye-bye if I like the S&W more/better....)

It ran FLAWLESSLY through four full magazines. I don’t know whether the magazines are NOW broke in or it’s because I sanded the followers with 2,500 grit sandpaper and sprayed the inside of the magazine with Remington DriLube.

But it’s NOW working even with CRAP Federal American Eagle! I’m now confident to carry it with Elite Ammunition S4.

From S&W customer service
Thank you for contacting Smith & Wesson, the sights on the 5.7 are like the ones that go on our shield series firearms (not our full-size 2.0 firearms) and the optic cut is SMS.

Fastest Factory FN loading: SS198LF. You're looking at 2,050-2,200 fps out of the handguns depending on temperature and barrel length, and upwards of 2,500 fps from a 16".
Fastest round personally tested by myself exclusive of manufacturer's claims: Elite Ammo's S4, and T6B.
I've clocked the S4/M/UR variant at 2,400-2,450 fps from the handguns.  I've clocked the 28gr variant of T6B going 2,375-2,400 fps from the pistol. It's been a long time since I've used T6B. At one time it was 32gr, then he cut the weight back down.

Along these lines, have you ever done a head-to-head comparison between the BDF and the T6B? I'm curious which one is the better performer in gel/armor based on your testing.

It's slower; about 1950-2100 fps depending on the lot. The first couple of lots I got from VG were at the introduction of his new brass so they were carefully working up loads.

I try to avoid head to head comparisons as in general most manufacturers don't like it, and since I'm poor I rely heavily on donations of their ammo.  The barrier performance claims of EA's super rare copper choice really haven't been quantified as being any better than BDF. The softer copper in the BDF and lower speed will lose out to the T6B against soft armor though.  I truly wish a bigger agency would demo the copper exotic loads and give us more data to see which one would come out on top.

Makes sense, thanks for the detailed response!

Have you noticed any difference between the two alloys as far as fragmentation in gel tests? I can't decide if I think the softer alloy would break up more reliably or at lower velocity, or if the harder one would due to brittleness?
