Thats quite true, But there is also a hell of a jolt when bullets hit the plate and while in might react well to a hammer hitting it how will it last with the inertia of a bullet impact repeatedly? A 20 oz hammer doing 20ft per sec (light tap ) is 8ft/lb. I bullet impact will be a near instantaneous impact nearly 10 times giving it a decent swing with a sledge hammer (8lb sledge at 50fps is 49 ft/lb ) There is a lot of energy transferred. The reduction of impact as carried through the post may well see the gear last longer .....

I really like the idea and I am not trying to be critical. I am trying to see if you can do this isn a way so that you get a decent life out of it. It sounds very interesting.
