I have read a lot about Hydrostatic shock but have never experienced it.
Reading research on sites like Nathan Fosters Terminal Ballistics the consensus seems to be that Hydrostatic Shock starts to take effect from terminal velocities of 2600 fps and upwards.
My MV is 2970 fps so I have shot a lot of deer of all species with a terminal velocity of 2600 to 2850 fps using a Nosler 120 BT. Most are chest shot, but none of them drop on the spot, I always get the classic back legs kicked in the air and take off 20 to 60 yds before falling over.
Is it the speed or is it the fact that I'm using a fragmenting bullet?
I have shot plenty of foxes in the chest which have dropped on the spot, probably from Hydrostatic Shock, using a 70 grain bullet at 3600 fps. But how fast does a bullet really need to be going to get the instant drop on the different species of deer from a chest shot?
It would be very interesting to hear from SD members on the subject.
1. How often have you experienced it?
2. What species were you shooting?
3. What terminal velocity was the bullet running at?
4. What type of bullet were you using?
With all the experience on this site we might even get some valuable research out of it.
