ID a Pistol by Primer Strike?

[1SOW]

Just curious:
I've picked up some (8-12) 9mm  R&P cases that simply won't resize normally.  Two or three passes through two different LEE carbide sizing dies and .375+ at the case mouth is as small as they will resize.  Every try to resize feels like an "unsized" case pull on two different presses.

These cases' primer strike look just like a CZ full size strike but surrounded by a teardrop shaped indentation.

Anyone know pistol makes that mark?

The primer indentation sounds like primer swipe, where the slide starts to unlock before the firing pin has fully retracted.

As for the size of the cases, some chambers are larger than others, especially in full auto firearms.  Some pistols also have overly large chambers, like the M-11 pistols, which are made to shoot anything, but not made for the cases to be reloaded after firing.

Hope this helps.

Are you sure they are not 9X18 cases?

The cases are marked the same as all newish 9mm R&P and have the "new look" , very bright shiny base with the pronounced "moat" bevelled  primer holes.  Some of the older ones I load have a flatter looking base if that makes sense. No distinguishing marks.

I haven't run across this before.   

Sure looks like a FP strike indentation.  ALL that won't resize have a round FP indentation and a classic teardrop indentation evenly  surrounding the the center hit.  Like aodified Glock strike.

1SOW,

They aren't brass plated steel cases are they?  I know that those are floating around now.

There's always that possibility.  Touch them with a magnet and find out.  S&B is using a process that looks exactly like brass, but is brass plated steel.  Others may be doing the same as well.

Hope this helps.

I understand that even the steel can be reloaded, although not preferred. Is that correct?

[1SOW]

These are R&P cases.  I did go out just now and test them with a magnet.  They aren't ferrous metal.

I don't use ANY S&B for that reason.  A friend accidentally used a reloaded coated steel S&B in his open gun.  Bad juju!

Good call.

Some European made 380Auto is labeled "9mm Kurz" becasue it's literally 9x17mm. I've mistakenly picked it up on the range and thrown it into my bag after seeing the word "9mm" stamped on it. Russian Makerov is 9x18mm, and Luger is 9x19mm. 9x21 and 9x23 are also common. So "9mm" is not always ParaBellum.

According to the article I posted, Freedom Munitions doesn't recommend reloading their brass plated steel cases.  Not sure what other manufacturers are recommending?

Steel doesn't have the elasticity of brass, so it's prone to cracking sooner.  It's probably harder on dies, particularly steel sizing dies, too.  With so many brass cases available, I see no reason to try reloading steel cases.

Hope this helps.

Folks shooting 9mm Major PF SURE don't want brass coated steel cases.
