The hydro shock is a real phenomenon but tends to get over-hyped. With a short distance, good remaining velocity and relatively blunt nose (as the fusion bullet) vice sharp pointed one or fmj, there definitely can be a knietic energy shock transfer from bullet to body. Decent article I read a short while ago said most bullets need to be going at least 2400 ft/sec in that writer's opinion. I think it has to do more with the relative amount of KE transferred and if done to the CNS... which your high-lung shot at 80 +/- yds would do to the spine. Think of what a 1000 ft-lb force from a 2x4 at that location would do... heck even 750 up near the spine. SMACK!!!
Well said. If I had to put a number on the velocity at impact it would be close too 2300 fps.
Surprisingly when I ran the fusion ammo over the magneto speed this summer it was slower then advertised.
Federal says 2500 fps avreage from a 16 inch barrel. My AA barrel was just barely over 2400 fps at the muzzle.
Still found it interesting to see that happen. I'm not a vital zone shooter for sure but figured it would be a good chance to see what it would do at a longer range then last year's deer.
If I get anouther chance this year to get a shot like this again I will take it just to compare it but after that I'm going to start shooting the high shoulder again with this bullet and then try a diffrent bullet on a few vital zone shots.
Lil testing never hurts.
