Picking the appropriate guide for the work is a larger deal than you could expect. We do not give primers a lot of focus, but they have the most essential work in the cartridge "go bang" process.

For absence of a better word, you'll see a little "nub" that extends into the primer pocket area of the situation.

Because of that, Berdan instances have two flash openings on either side of the anvil. The guide itself has no interior anvil, so the compound is pushed against the anvil component of the instance to create ignition. Both types are practically reloadable, but Berdan is a royal discomfort in the butt.

Those are simple to get rid of from discharged situations. As the flash hole is in the facility, a pin in the resizing die merely presses the invested guide out the base of the instance. Easy peasy.
