Whats the point of a berdan primer? Are they cheaper or easier to make or something? Seems dumb, why did russians use them for so long?
>>64564848They work just as good (theoretically maybe infinitesimally better) and it's cheaper to make the anvil as a feature in the primer pocket than as a separate piece. It's not better or cheaper enough for anyone else to bother with.
Berdan ostensibly are slightly more reliable and were more reliable for long-term storage. These days I doubt that there is a performance difference, but during the cold war buildout I'm sure that it was a soviet consideration. There's also the possibility that soviets had better access to the raw materials to make berdan domestically.
>>64564848Berdan is older, russians cannot into modernity.
It makes no sense. Why would you drill two holes, both off center, when you could just drill one dead center?
>>64564848I have absolutely no evidence to back this up but it wouldn't surprise me if the Russians simply received presses for berdan cases and primers and simply never bothered to change the design to boxer. In their defense, from a military perspective it makes absolutely no difference and if you already have 1 standard in use. There's really no point in transitioning to another for something as useless as reloading
>>64564900Because the center of the primer pocket is the anvil.
>>64564848>Are they cheaper or easier to make or something?yesboxers have an anvil in the primer. a separate component that needs to be added.so boxer primer itsself is more expensive
>>64564848that's two flash holesthat's twice as big as oneliterally 200% flash holesit's self evident
>>64565200checked
>>64565200even western ammo is decadent
>>64564848>why did russians use them for so longWhy have the Russians used Kalashnikovs for so long? It meets requirements and they're tooled up to make it, so why spend extra money to change things?>easier to make or somethingHypothetically they hold more priming compound and feature a more direct route for the primer detonation to reach the powder. It's not a factor today. 100 years ago, it was absolutely a factor. Do some reading about the trials and tribulations that the US had to go through in its efforts to produce a reliable non-corrosive primer. There were a couple of problems, but according to Hatcher, none of those problems would have been problems if they'd simply switched to Berdan priming.
>>64565200How does the anvil work then? Does it pinch the explosion?
>>64564900Those holes aren't drilled, they're punched in the same pressing operation that forms the head of the case. It's just as fast to punch two holes as it is to punch one.>>64567269The anvil is just a hard surface to crush the primer mixture against.
>>64567269Pinching the primer compound between the firing pin and the anvil is what causes it to explode.
>>64565200what's the red stuff?
>>64567448it is there to show the rest of us who is colorblind
found these 3d graphics a bit more explicitwish we could talk more about such topics and their diys but it's probably banal to most people as everything always already starts at the primers, never making your own from scratch like it was with percussion caps and nipples
>>64568570Chinese has more parts but each part is maybe simpler.But would the chinese assembly gradually fall apart? Does the sphere ever disconnect from the sharp edges from the triangle aperture?>it's all snugged when the cap is rammed in.Over winter/summer cycles of a decade or two, though?
>>64567448Kroovy, my brother
>>64568570One of the reasons why I constantly shill this book is because it explains how primers were made historically, their evolution and various formulations. This information is no secret, it was put in print over a century ago.
>>64568613I would think that the ball is larger than the triangular aperture, so it can't simply fall through.
>>64568636your 'tism is appreciated but unfortunately from historical context alone i'd still not be smart enough to extrapolate simple "go to homedepot, get M3 screw and M5 closed nut, push sheets of can of soda with M3 in M5 for primer cup">>64568640three flash holes essentially
>>64564902that's basically it. Berdan and Boxer primers were both invented in 1866 and the Russians spent a lot of money upgrading their rifles to Berdan rifles beginning in 1868, which actually made them one of the earliest countries to adopt a modern-ish centerfire rifle. And then they just kept making berdan primed cartridges, because they already had already committed to building the equipment and institutional knowledge to do so.

>>64565794Where do you think Hiram Berdan came from?>>64569067Kek.
I have read that the boxer primers have been adopted because insurgents dont have the machinery/capability to reload boxers. No idea how true it is
>>64568636it's a good topic (and that book is worthwhile)
