Oddly, Berdan priming was invented in this country, but used in Europe and other places.
Boxer priming was invented in England, but is used in the U.S. Go figure. :?

Anyway, conventional loading dies in the U.S. are designed for boxer primed ammo reloading.
A single flash hole in the middle, compared to a double flash hole that's side by side in Berdan priming.
One picture is worth a few words....

Berdan priming on the left, Boxer primed case on the right.
Cases were cut in half with a tubing cutter, for ease of viewing.
Australian 7.62 NATO on the left, .30-30 Winchester case on the right.

What advantage is there to a Berdan primer over the Boxer? Would there be faster or more even burning of the bullet powder?

I suppose there might be an advantage to the burn with double flash holes.
BUT, from a reloading standpoint, the single flash hole is much easier to deal with.
You can reload Berdan primed cases, if you have that type of primer, and if you have the
tool needed to deprime them.

RCBS makes a tool. But again, check this:

Includes case holder and wrench.
Tool hooks edge of berdan primer and levers it out of the case's primer pocket with a pin in the end of the tool.
Primer-removal process is significantly slower than decapping boxer-primed cases.
Replacement pins are available, product number 134-121.
RCBS does not recommend using this with crimped-in primers (military crimp).
( And a lot of foreign military ammo uses crimped Berdan primers. )
