Know this about shooting (primers only) in any revolver: You must enlarge the primer flash hole considerably or the primer will cause enough pressure to build in its primer pocket and push the primer back and into the firing pin where it will tie up the rotation of the wheel. This does not occur when the case is loaded with a charge and a bullet because on recoil, the whole case is driven back hard into the frame and this reseats the primer in a nano-second. Without the powder and and bullet, the case stays forward and the primer only goes back. Interenal primer pocket pressure wants to spit the primer.
I have tried this several times and have had to work at getting the gun open as the primer flows around the captured firing pin. You have to experience it to appreciate the pain in the ass it is.
When you open the flash hole, you let enough primer pressure out fast enough to stop the ejection of the primer from the pocket. Do not them reload the opened flash hole cases with a normal load later as this might be more exciting than you think. You could get a load of fast powder to detonate. Maybe.
