I bought some "S.T. Action Pro Trainer Dummy Rounds". They have a metal rim, translucent plastic hull, and some orange plastic as a stiffener inside. They are not the right weight, but as mentioned by others you can add some weight inside them if you wish. They were $2 a piece. I bought 12. They appear to be more durable than the Tiptons, which as you have seen can separate at the rim and become jammed in the magazine tube or chamber.
