For 44 Spec/Rem Mag
Cap 1 - 1.15gr Clays, No Crimp Hand fit + Reg Large Pistol primer + Speer cap filled with GLITTER!
The charge of clays is enough to push the Cap out and with enough force that it will shatter on impact rather than inside the barrel.
Anyone else came up with some fun things to do with these Speer Caps?
