    Probably the same as a watermelon or a cantaloupe.

    A quick google search came up with some different thoughts and estimates from various sources.

    Search phrase “zombie skull newtons of force”

    The aluminum baseball bat is arguable one of the most popular mid-ranged weapons against zombies, and is so for good reason. An aluminum baseball bat is slightly over 3 feet in length and 33 ounces in mass. Sports stores are commonplace in cities and thus, baseball bats are plentiful and incredibly easy to gain access to should an outbreak occur. Bats are relatively light, easily handled and transported, and do not require much force to induce fatal injuries as I will demonstrate below.
    A simple fracture in the human skull can be caused by as little as 73 Newtons of force. An unrestrained adult falling to the ground can produce more than 873 Newtons, which is more than enough to fracture the skull. The upper bound of 873 Newtons converts to approximately 196.26 pounds of force required to fracture a skull. A study of a baseball bat swung at a ball produces forces averaging 4124 pounds with peak forces at 8314 pounds (20-40 times more force than necessary to fracture a skull). Even with a relatively light swing, a baseball bat can easily crush a human skull, causing tremendous brain damage, especially if aimed at weaker sections such as the temples.

    The LB doesn’t matter so much, the design and fps matter. Its hard to say, I will try to do some research to see what is required but there’s not much on it. To low and it wont kill, to high and you risk damaging the bolt. I remember seeing this video- https://www.youtube.com/watch?v=x22qp7-XoXY . it might help.
