Microstamping is viable (allegedly)

New Jersey AG said:→
Attorney General Matthew J. Platkin today announced that, based on both live-fire testing results and existing peer-reviewed studies, microstamping technology is a viable means of matching an expended cartridge case to the weapon from which it was discharged. This finding represents an important step toward establishing a roster of microstamping-enabled commercial firearms, as contemplated by P.L. 2022, c. 57. Governor Phil Murphy signed that law in 2022 to facilitate the rollout and adoption of microstamping technology for firearms made available for sale to the New Jersey public.
...
"This technology gives law enforcement an innovative tool to identify crime guns and bring perpetrators to justice," said Attorney General Platkin. "Now that we have certified that this technology is viable, we urge gun manufacturers to adopt microstamping technology in their production facilities and apply for placement on New Jersey's microstamping-enabled firearms roster."
...

Presumably NJ urges criminals to use only microstamping firearms in their crimes.

I'm 100% betting in all the testing they never 'tested' how effective 5 minutes with one of these was at defeating the 'viable means'...

 

Someone with good mechanical knowledge might not be too concerned about microstamping.

Tell me how this works with reloads. 

Reloads - to be illegal !

Must buy New brass from government approved supplier at government approved cost with government approved license through government approved shipping method IF your government approved Social Media Score has been approved through government approved agency AND IF the government approves payment through your government run digital currency system.

Get the idea?  NEVER give an inch !

I'm missing how this has anything to do with it.

 

Microstamping is supposed to leave ID markings on the primer and the brass.

In order to logically work, this implies outlawing reuse of the brass.

Is it a mass shooting if a casing is found that appears to have been fired by 4 or more guns?

It also includes redesigning every firearm made, they don't hit brass if they did then no go boom (unless it's a rimfire) and there's a reason they stopped. 

History of the rimfire from 1859 to say 1873.  ;)

I don't know how viable this actually is, the primer is what is going to get stamped correct?

 

Having recently taken a reloading course, one of the things you look at is the primer to see if there was an over pressure or not.

 

AND

Without writing a chapter....

When the firing pin hits the primer something happens, the primer goes boom and ignites the powder. When the powder goes off there is an explosion and the case actually expands a bit and contracts. This would happen to the primer as well, that's how you can tell if there was an over pressure. I haven't seen where an over-pressure pushed out the dimple caused by the firing pin, but I am pretty new.

So I would imagine small marks on the primer, are going to get slightly distorted after firing completes, so you wouldn't have an EXACT match but a likely match.
Not to mention I don't know what the tolerances are but I don't know that the firing pin is hitting the round in an controlled enough angle to prevent any streaking, then there are the slight differences in the casing and how it seats.

Color me skeptical.

The primary microstamping push is for the firing pin to leave an imprint on the primer, but there is also breech face microstamping that would stamp the head of the casing both seen in the attached photo...

Breech face assumes it doesn’t land on the stamp like Speer, 40, S&W, etc.

But who needs to know caliber and differences between .38 and .357, you should be able to just tell the difference.

Hmmm, wonder what the minor FP swipe like on some P365’s would do to their micro stamp….

Looks like it ALWAYS hits dead center too right?

I would suspect if they mandate breech stamping they will manate the manufacturers do their stamping within a certain radius leaving a clean area for breech stamping, or mandate the manufactues laser etch vs stamp...  Just like I would think they would mandate primers be flat surfaced and not patterned that was actually a thing at one time https://forum.cartridgecollectors.org/t/primer-markings/38791

That's called ammo serialization and is totally different and equally F'd up.

Those primers actually look pretty cool with the designs, you would at least know which ones your using.

I was not talking about serialization I was talking about a potential law limiting manufacturers from imprint stamping the head of the bullets and instead being forced to laser etch or something else as to leave a clean smooth surface for breech imprinting...

Yeah they are cool, I'm kind of surprised that a niche market for reloaders has not spawned as it would be a cool way for reloaders (especially the bigger ones) to brand their reloads...

Gotcha.
Totally on point.


The laser etching would use some of the same technology as serialization.
