Re: steel target question
It would depend on several things. How thick are the paddles, How big are the paddles, what weight bullet, If you close one eye or not, etc. Dueling trees are made differently by different companies and that would make a differance also. I would think a .308 would flip the plates out as far as you could hit it. Even past 1000 yards. Try shooting one with somthing small like a 9MM out to a distance where it won't flip it any more and figure out the energy it took and compare that to the .308.
