Today was the opening day of the muzzleloader season here in the peoples republic of Massachusetts. About 8:00 am I shot my firs deer with the new Omega. I used a 250 shock wave bullet pushed by 120 gr. 777. I wish I didn't drown my camera in the river so I could show you a photo but the entrence hole was huge as it hit the back bone but the exit hole was small, I know which was which as I was in a tree stand. I can't figure this out, Any suggestions.
Ever throw a stone into sand and seen the sand spray? That shockwave crushed and pulverized the spine, even where the bullet made no actual physical contact with the bone crushed by its shock wave. The bone debris blown from the crater cut and tore flesh around the original entrance hole enlarging the hole even while the bullet was passing through the spine, leaving a tremendous hole. Alot of the bullet's energy was dissipated rapidly (just like asteroid striking the ground) and when that happens, alot of energy is dissipate at right angles to the motion of the bullet, leaving, literally, a crater.
Check out the "don't over drive powerbelts thread". It provides another example of rapid dissipation of bullet energy. Lots of surface damage, huge entrance hole.
