Many, many years ago I read an article about a device used to decap
Berdan primers. it was a device that used the power of a standard boxer
primer to remove the Berdan primer. The only thing I really remember
about the article other than that was that the reviewer said it worked
perfectly, which is not common for Berdan de-capping devices. I'm sure
there are a number of ways to accomplish this; the reloaders in Europe
must have some system that's relatively easy to use.

As far as de-priming, I've heard of 2 ways. I've seen pictures of a tool that
looks vaguely like an old fashioned can opener that hooks to the rim of the case
and levers out the spent primer. Another method I heard recommended is to fill the
case with water, set it over a hole slightly bigger than the primer, and drive the
primer out with a dowel that fits snugly in the case mouth. The hydraulic pressure
of the water forces the primer out. Seems like a good way to take a bath. I
assume that Boxer primers will not work in a Berdan pocket and I have never seen
Berdan primers for sale, but then I have never looked for them.
Good luck.

Easily done. Years ago, it was the only way to feed the SMLE.
RCBS makes a neat decapper, looks kind of like a bottle opener. Comes
with a peg to hold the case, you hook it over the extractor and a pin
punches through the primer dent and pries the cap out. Takes a bit of
adjusting to get it right (and miss the anvil), but once done it's fast
and neat (unlike the water and dowel or primer powered methods).
The Lee primer will generally seat the primers just fine (they tend to
be a shade larger than US. Old Western Scrounger will sell you RWS caps
in lots of sizes.

I've heard that people use a rod that tightly fits the neck of the
cartridge, then they fill the cartridge case with water and use
hydraulic pressure and a sharp whack to pop out the spent primer over
a hole big enough to let it pop out.
Here's an idea I haven't tried, but would like some feedback:
Picture using a dremel rig to remove the anvil bump in the bottom of
the Berdan primer pocket, and use a drill bit to open and slant one of
the holes toward the middle of the pocket, and then size the pocket
for a Boxer primer. If the crossection and fluid resistance of the
holse are roughly the same, and if the holes are such that they allow
the Boxer primer flash to pass unobstructed, why couldn't one do the
conversion> With a jig setup, it should go rather quickly.
RCBS sells the can opener tool.
The water in the case method also works. I use a steel dowel. Bring a
large bath towel.

You assume correctly. The Berdan primer uses a post on the case as
the anvil while the boxer primer has the anvil built in. Also, the
diameter of the cup is a little different. Trying to prime a berdan
case with a boxer primer will probably detonate the primer.
OTOH, if primers are ever taken off the market, it will be easier to
make berdan primers from scratch than boxer primers. So maybe that
berdan brass should be saved for a rainy day. I include Wolf's steel
cases in brass.

I wonder if anyone ever tried using hydraulic pressure to remove the Berdan
Primers, Say, fill the case with water, and use a tight, neck fitting, punch
and
tap it with a hammer.

RCBS makes tools for de-priming and seating. You can find them at
Huntington's http://www.huntingtons.com/
Huntington's used to sell RWS primers too, but I don't see them listed
anymore. Old Western Scrounger may be the only source on the web.

IMO reloading Berdan cases is not worth it unless the case is not
available in Boxer style. Not even then, if loaded ammo is fairly
easy to come by.
Happy Independence Day!

Something like ramming a post in a water filled post hole, Huh ?
A paper towel in the hand that guides the punch should cure the
problem.

It is posseble to buy a tool called "Hydro punch" that operated by the
method you describe. My advice is if it is posseble to buy boxer primed
cases in the calibre you are reloading don't mess around with Berdan.

I have done it several times. Two problems- getting primers, since
berdan primer sizes are not as standardized as are boxer, and getting
the old primer out. One of the reloading companies has a tool for
doing this, I made mine by grinding a scoop point on a broken punch.
It needs really good steel, as you tap it sideways into the firing pin
indentation and rotate down. I use a steel rod in a vise to hold the
case- must be a tight fit.. I was able to find Norma primers which fit
the Swedish ammo I was using.

I didn't have any Berden primed cases to work with, but this thread got
me wondering... so I've just finished deprimeing some .270 brass with air
pressure. Shell holder in a vise, rubber tipped blow gun, and PRESTO,
patented pneumatic primer popper! The next project is to rig a target and
backstop downrange from the vise :)

There are hand tools designed to pry the primer out w/o damaging the case.
If you have the air compressor and the primers are not too tight that should
work, too.
In Europe I saw a claw type Berdan decapper that grabbed the rim or
grove of the case and was then screwed into the primer which was then
pried out. This system stil managed to bend the posts on some cases.
Another just used a lever to scoup out the primer, and this also
damaged some cases.
Some years ago there was a device advertised that used the blast of a
boxer primer to blow out the berdan primer, so one had to have a boxwer
primer and the right sized berdan primer for every reload.
Some folks have made depriming pins for berdan primed cases. One cuts a
case just above the base to see exactly how far apart the flash holes
are or how far of center the single flash hole is and how big around the
flash holes are. A rod that tightly fits the mouth of the case has holes
drilled in one end and hard steel pins set in the holes to fit the flash
holes. The rod is placed in the case and turned until the rods line up
and fall in the flashholes and then the primer is tapped out the same as
with a boxer primed case. Main prblem is that as the flash holes tend to
be smaller on berdan cases, the pins are necessarily very thin and
easily bent if not properly aligned.
Some folks have swaged a boxer primer pocket into an existing berdan
case or gon so far ad to drill and tap the base of the case to accept a
screw in piece having a boxer primer pocket.
As has been pointed out there are more than two sized of berdan primer
and sometimes cases of the same caliber from different manufacturers
will have different size primer pockets.
By far the easiest way to deal with berdan primed cases is to write them
off as "non-reloadable" or convert a boxer primed case to the needed
dimensions.
Shoot, and reload, safe,
