that rock makes me cringe, i have done that stuff too. I was snickering at some guy loading his truck at lowes yesterday. Loading 60lb bags of concrete premis rather than the 80pounders. I found out about that years ago.
I found some 357mag brass, which i sized and belled, currently in the tumbler.
I was having some trouble with one of the dies, and ended up digging out 4sets of 38/357 dies, where did they all come from? And found a taper crimp so that's good.
One of the sizer dies was kind of unusual. It had the normal pin to knowck the primer out and the button for the case mouth, but that was attached to rod that did the belling.
never had that where you could size, deprime, and bell in one step. I am going to put some of those 358429's together and i have a model 28 sitting there so i am going to see the length thing for sure.
