This is specifically referencing the split pin portion of the question. Both the Lee classic cast and classic cast turret share the same slit pin design at the bottom of the ram. Early in my reloading days, I managed to break one of them, had to order the whole toggle link from Lee to fix it. Upon close inspection, the only reason it broke was because the bolt that holds both linkages together was slightly loose, allowing it to twist, which will break them in short order. As long as the bolts are kept tight, I have no worries about doing the most strenuous sizing possible on the Lee classic cast which I now also have. I'd go as far as to say one could use the press for swaging if your arm is up to it.
