It's a Lee. I've used and worn out half a dozen of them. The body of the tool is some sort of cast material and not steel...as a result they wear out after a few K of primers. But I always liked using them even if they are slow. You have such perfect feel and control of seating depth. Now I use the RCBS priming press...which isn't any faster the way I use it, but it has pretty good feel and will never wear out.
