Simple Hydrostatic Shock Test

We could go into the details of how the phenomena works, but hydrostatic shock works best when the target is smaller than or on the order of the same size of the bubble created by the impact.

If the bubble is small compared to the target, e. g. a water-filled 5 gallon plastic jug or deer, the hydrostatic shock from a .223 does little damage. Hit a 16 oz plastic container filled with water, however, and the thing explodes. Same effect on squirrels.

So, to see whether hydrostatic shock will be evident for your game, test your bullets on water-filled plastic containers at the ranges you expect to shoot at. The volume does not need to represent legs and head, just the body.

Yes, I have seen sixteen ounce plastic containers come apart when hit by a pistol bullet, especially if it is going the long way through.

Higher velocity makes the effect more pronounced.
