[QUOTE="LVJ76, post: 1651670, member: 108965"] Not necessarily, on larger bore calibers like the .338 and .358 hydrostatic shock can occur at lower speedS, also with a 30 caliber bullet. The smaller the caliber the faster the bullet must impact. The larger the caliber the bigger margin you have. I've killed several deer with my 7mm-08 with a 139gr SST, all shot behind the shoulder and most dropped in their tracks with no movement afterwards. Muzzle velocity is around 2,800 fps with impact velocities between 2,650 and 1,900 fps. What bullet you use also plays a role on this, a bullet that causes a wide wound channel with good penetration will kill faster. Now I said "Most". I've had some run 100 to 200 yards and I cant understand why. One I actually hit in the forward part of the shoulder, destroyed heart and lungs and 2" exit hole behind the opposite shoulder and still ran close to 100 yards. How? Why? Don't know, but it did, it was deader than dead but it still ran. With my 7mm Rem Mag I've had better results than with the 7mm-08, more likely to Boom Flop. Now since the bullet is going faster I also use a tougher bullet like the Interbond or Accubond so it doesn't blow up on impact, or a heavier bullet like the 154gr or 162gr SST. I've also seen DRT's with .223 Rem and .243 Win, proper bullet placement is key along with the right bullet for the task, and also staying within the capable range of the cartridge being used.
