Here's a question for y'all...between the Lyman 450 and the RCBS Lube-a-Matic, does either provide any meaningful advantage over the other? I've used a 450 for nearly 30 years with no valid complaint, but an RCBS unit has fallen in my lap and I intend to sell one or the other. I have heater units for both.
IIRC, I've used Lyman and RCBS dies in my 450, but I'm not sure whether the top punches are interchangeable. What's the deal there?
