Just reloaded about 67 44mag shells last night. Of the 67 about 7 were unusable. Some of the bullets tore the brass about half way to the bottom of the shell. While a couple shells just got a nice dent in the side. I threw the bullets, brass and powder away that messed up. Ive never had this kind of waste reloading. I bought these reloaded from a gun show and step dad says it may just be bad brass that has weakened. Of my 30/06 Ive never had this happen.
