I bought a Rossi Puma in 357 about a year ago and just got around to shooting it. With either 38 Special or 357 ammo, after ejecting, the case wall has a gash right at the mouth. I'm concerned that the cases will split after reloading. I have a older Rossi in 44 Mag that shoots great and do not have this problem so this caught me by surprise. Anyone run into or heard of this problem?
