It's even more toxic than that, about 16X the strength of a Diamond Back.
With about 7,000 snake bites yearly in the U.S. only around 1% are fatal, Of course that doesn't take into account the other damage to limbs, nervous system, etc. Not to mention the cost of Anti-Venom. A vial can run $2,000 or more, and easily need 10 vials or more if the venom gets into the system. That's enough to kill ya right there. :E Thank the drug companies for that.
The baby ones here are the worst. We call them no-see-ums, they are very small, 6" long or so, haven't got their coloring yet, and blend into the garden rock. The babies will release all their venom, basically because they don't know any better. These are the ones that we worry about the most, for us, and the dogs.
It's that time of year here, have seen two adults in the last couple of days. Time to start looking again where I'm going.
