How to identify boxer and berdan primers

[Vulpatrix]

I need help, could you identify the type of the primer here ? This is the inside of a bullet.

This is the outside

It's the inside of a cartridge, not a bullet. And 2 flash holes means it's Berdan. You really can't tell one way or the other from the outside. Kind of odd for there to be no head stamps though.

I beg to disagree. Other than the distinction between bullet and cartridge, everything you wrote was perfect. English has become so widespread that we sometimes forget everyone else doesn't speak it.

Welcome!

Most cannot reliability differentiate from the exterior.

I don't usually know until my press doesn't complete the stroke or my decapping pin breaks off.

Yep, two small holes like yours it's Berdan, one much larger hole dead center and it's Boxer.

Berdan on the left and Boxer on the right.

Welcome to the forum.

I think the correction was only to prevent a mix up.

As you see from the pictures above your brass case is made for a Berdan primer.

Come back any time and if you need help explaining anything we are happy to help.

Berdan invented by an American, boxer invented by a Britt. Funny how the prevalence reversed.

And, for all reading this, not all Berdan primers are "corrosive".

Just felt this was a good place to add that since, apparently, there are still quite a few folks out there who think Berdan = Corrosive.

And ... Welcome to THR, Vulpatrix! We hope that you stick around!

The key thing about a Berdan primed case is the off center flash hole. Most Berdans have two flash holes but some have three and some have only one.

Some of the first non-corrosive primers were Berdan because the mix was not very "hot" and the Berdan primer cup has more room for more priming compound.
