Sorry I thought you meant you were reloading what you’ve fired.
Loading is fine.
I also wasn’t aware they sold primed unloaded NAS3 cases. Where are you seeing those?

You can get them directly from Shell Shock:
1,000 5.56x45mm Cases | Shell Shock Technologies
1,000 new unprimed NAS3 5.56x45mm cartridge cases. Shell Shock’s NAS3 cases: Up to 50% lighter than brass cases Offer greater lubricity and will not abrade, clog, foul, wear-out or damage breach and ejector mechanisms. Offer greater corrosion resistance, tensile strength, and elasticity than...

Yeah, I know.
He said ‘primed’, those are unprimed.
I get the initial loading and then maybe 1 in 4 or 1 in 5 casings will resized for reloading. SS says in their faq section that rifle cases are not reloadable
Haha..my bad. Yeah, Shell Shock doesn't sell primed cases.
There were some listed here as primed, but they're OOS (the link says "unprimed" but the actual page says they were primed with Genix SRP):
ETA: that place still has some primed 300blk & 40 S&W NAS3 in stock.
None of mine would resize for reloading. I tried about 100 and gave up. I’ve shot about 1.5k and just leave em.
Black Arc has announced 6 ARC ammo loaded with Shell Shock cases. There will be two versions. One loaded to semi-auto pressures and one loaded to bolt gun pressures.
No word yet, that I've seen, on price or expected delivery dates. Also no word on which bullet(s) will be used.

I believe the biggest gains are in shorter barrels for these.
Badlands 77gr shell shock fired from a 12.5 criterion core with a griffin explorr. This is the most recent batch
The mk12 with the can and mk262 is rated at 2750.
I'm essentially getting the same ballistics out of a 12.5 now that I would traditionally get with an 18"

I've looked ar these shell shock cases when they first came out in 9mm, many yrs ago, but never tried them.
This has been going on for like 35 yrs with the SS case heads...we are seeing sucess, with Federal Steel, Sig hybrid, & Shell Shock...they have merit, and brass cartridge cases are very old, and we need improvement here, along with the powders to go with the new case technology.
The 9mm are a hybrid case with Stainless Steel case heads and alum bodies...and reloadable with their ejector 9mm dies.
The 5.56 are not hybrid cases but a two piece stainless steel case, head & body.
They have a larger flash hole as a means to crimp the body to the case head
I haven't seen dies to reload them, ejector type or any other ...I'd have to give it a try or make dies to do so.
They say an 8% increase in case capacity, but the velocity increase will likely come from speciality powders.
Remember Hornady’s line of Superformance ammunition achieved significantly greater performance with the exact same brass case and bullet, because of powder optimization, not greater capacity.
Stainless case heads are not hot when they come out of the gun... that is true.
Since energy can not be destroyed but only converted or changed, the Stainless cases will impart more powder energy into velocity instead of absorbing powder energy into case head in the form of heat...which will impart a bit more velocity to the bullet under the same pressure, so stainless is a more efficient vessel.
That said, the larger increase in velocity is due to most likely a specific powder blend for the bullet. Ya see it all the time with some of the new powders a 150 fps faster in the same case, but change bullets a few weights heavier and the advantage disappears.

Phantom Defense is also using the NAS cases. I picked up a few hundred 556 77gr TMK rounds. Advertised Velocity is 2900 fps (18" barrel). I have only tried them in my 26" Bolt gun and got 2995 fps average 5 round 100 yrd groups averaged .66". I bought it to see how it works in a 14.5 AR but haven't had a chance yet. Actually Pretty happy with it.
What are the odds that the steel cases allow for high pressure loads without the warning signs that brass would have? So shooters think the ammo is fine but are in reality running 70K PSI loads.
I loaded a few NAS3 cases with 27.0gr of AA2520 and a 77gr SMK and got slightly over 3000fps from a 20in barrel. No "pressure signs" or erratic function, but I have the feeling it was too much. Not planning on doing it again.
The steel case does allow for much higher pressures than normal.
But in the AR platform you are limited to the same pressure as the brass cases...as the video states they are running slightly lower pressures and still achieving greater velocities.
How is this possible? Despite their claim to 8% increased in case capacity, our normal canister powders won't do that big of any velocity increase.
Staying with Max pressure of the 5.56 and adding the 8% increase in case capacity only gets you 56 fps with CFE223 and a S109 63 gr fmj in a 20" barrel.
The difference in powder charge was 27.9 to 30.78 grs of CFE223 but only gets 56 fps increase in velocity.
For the average guy it would be better to buy the loaded rds and forget reloading since it also appears hard to size the cases for those who tried.
I shoot lots of Sig hybrid cases, in various calibers, and they can be readily sized.
You can only push the pressures in bolt guns, and Not in any of today's civilian ARs which are limited in pressure by design.
As Hornady shows in it's load data manual with the 6 mm ARC, divided by Auto and bolt gun designs for that cartridge.

You are totally out of your mind!
I'd call you all kinds of names if it would do any good. STOP!
To Others....Warning...
DO NOT load this in any AR!!!
Of coarse no pressure signs ...that You recognize!... because you are totally ignorant of the stainless steel case head, and what to look for.
This is why I don't like give load data and if I do try to explain how I got there, with the hybrid cases.
Few follow directions and take short cuts, thinking it doesn't matter it chambered in my rifle...wrong.
There are so many fuckin morons on this site.
QL says 3034 fps at 78,609 psi in a 20" barrel with your load, at 2.260" mag length.
Do Not Do This Again! So you'll be around to learn from your mistakes.
If ya want the velocity they are getting buy their loaded ammo...as you may not have access to the powder that gets the velocity at the requirements of the AR pressure limits.
Look at the last two posts. The steel of an action is the pressure vessel that contains the controlled explosion going off in igniting a cartridge. No matter what material which the case is constructed.
A bolt action has a lot of steel, an AR, not so much. The AR only has the barrel extension and the chamber of the barrel to contain this with some rather small lugs on the bolt, surrounded by aluminum.
Believing that a steel or hybrid case is going to allow ignoring pressures is not safe. You can only shoot proof loads so many times before something will let go.
