Give the strength of 'mild steel' please.
Hmm. Good questions. To which I cannot give definitive answers. Sad

CMU blocks appear to vary in toughness and thickness, which would affect the maximum range at which they can be penetrated.

I have no idea what the spec is for the steel used in US Army tests, or where to find it. But IMO, any "mild steel" is okay for informal testing, as long as all rounds are fired at the same plate. Obviously, the strength of the particular "mild steel" used would (as with CMU's) affect maximum penetration distance.
