M91 “Calvary” Carbine for my son

[oldfoneguy]

My son is asking me if it’s ok for him to practice shooting his new carbine by dry firing? Will dry firing these cause damage?

I never recommend dry firing for anything. I even uncock my Carbine, Garand and 10/22 without dry firing them. Many will disagree with me. I can recommend using those spent cases until the firing pin hammers down the primers to the point it doesn't touch them anymore.

Do you reload? If so remove the primer from a spent round insert a properly sized piece of urethane in the primer pocket, put in a bullet to cartridge spec length and crimp ridiculously tight. Then drill some holes through it so that it can't be confused with a live round and you have yourself a dummy round safe for endless dry fire practice.
