**600hp sbm block limit? Or is it bs!!**

Ok, all have heard all this "talk" that a SBM Block has a limit of 600HP before it Grenades, as far as I know it is all BS. I am not saying the it is not true but would like some actual proof from an end user.

Post your Broken Block Pictures along with a Story as to How it actually did Fail or Break and at What Power Level.
