Can load most moon clip guns without clip.
Because of spacing, ignition may be iffy.
Extraction will require a wood or plastic rod on some cylinders.
Some charge holes will let case fall out.
I found that nickel cases came out easiest.
My experience is with 9mm, .40, .45 and 10mm moon clips.
Not .38 or .357 guns.
