I have been running RCBS Load 2.88 since it first came out.
It got a bit wonky when I went to Win 7 pro 64, but I got by with an occasional reload from the CD.
Now that I am running Win 10, RCBS Load 2.88 goes straight to a fatal error message when I try to start it.
Does anyone know when RCBS load 4 will be out? Or what is a good alternative for interior/exterior ballistics?
I may have to break down and learn how to run a "virtual machine". For now I am getting by with the Hornady online calculator.
