In all 30 cases, autopsies revealed injuries distant from the main wound channel due to hydrostatic shock.
Thus, the result in a target is a rather small .223-calibre bullet hole, instead of a much larger wound channel.
The.22 was a naturally quiet caliber to begin with, and its soft, all-lead bullet often broke apart and ricocheted within the victim, creating multiple wound channels.
However, the wounding potential of M67 is mostly limited to the small permanent wound channel the bullet itself makes, especially when the bullet yaws (tumbles).
That opens up the bullet to a larger diameter; the wound channel is more severe.
These bullets are designed to penetrate deeply through muscle and bone, while causing a wound channel of nearly the full diameter of the bullet.
Maximum wound channels.
The massive nose provides a large surface area for producing large wound channels, resulting in rapid incapacitation, and the heavy bullet provides excellent penetration.
A bullet will destroy or damage any tissues which it penetrates, creating a wound channel.
Some bullets are constructed by bonding the lead core to the jacket to promote higher weight retention upon impact, causing a larger and deeper wound channel.
