Sorry Miller...I misread your post..You said nothing about doorknobs...and the one I made copying Stan has come to be my go-to on the range. Plus It'll deliver quite a whack if need be.
The "double ramrod" was sort of a joke/experiment as I was working on the ergonomics of trying to keep up in sporting clays with my buddies. It actually worked on the range. But it is clumsy and I didn't gain many seconds if any by using it. It was just whimsey. I enjoyed playing with it though. It's now disassembled and just a figment of imagination in a history of gun accessory dead-ins.
