(I imagine this is not entirely true since the containing tube will probably collapse it to some extent.)

This then brings us to the issue of the wounding effect relative to the sive of the temporary cavity. It is hard not to be impressed by the size and violence of the temporary cavity shown in ballistic gelatin in slow motion movies though some people seem to manage this feat without difficulty. We can see a similar impressive bulge of tissue caused by bullets shot into dead human or animal bodies and it seems obvious to me, though not to many, that such a bullet wound must incapacitate a considerable volume of tissue outside the permanent cavity to a decreasing extent as the distance from the bullet track increases. I find this a fascinating subject but I have spent enough time on this for now.
Thanks for an excellent explanation.
