[QUOTE="greenejc, post: 1705858, member: 60453"] Yes, but not as well. For a projectile in .308 or smaller caliber to deliver hydrolic shock, it has to be moving above about 2000fps. For hydrostatic shock to be delivered, it needs to be moving around 2500fps. This is on Whitetail deer. On larger animals, add around 100fps.
