I bought a box of 44 mag 240 jsp yesterday. Loaded up my 29, fire 3 rounds and it locked up. Opened the cyl, found a shell sticking out just a hair, ejected all the shells. The shell that was stuck out had split on both sides all the way from one end to the other. Tried my reloads, tried some federal. They worked fine. That is the second time in the last year or so Ive bought winchester ammo. The last time I had a round that would not chamber in my blackhawk. Took it home, and pulled both bullets out ofit, yea it had a second in backwards. I will not buy anymore winchester ammo.
