[QUOTE="chiefmoose, post: 1724439, member: 72217"] There are many factors in the expansion of a bullet. Velocity is a big factor, but density if the tissue it is being shot through is the biggest factor. I am an avid hunter, shooter, and reloader. I have been shooting my entire life. I have been reloading for 30 years, for both accuracy and terminal expansion. I have studied, and been involved in, ballistics testing. If someone tells you that higher velocity equals better expansion, is flat wrong! I have shot into many different ballistic media, as well as live animals to determine the best bullets for different situations. For hunting medium sized game at any range with a .308, in most conditions, your best bullet for accuracy and terminal expansion would be a Sierra MatchKing 168gr BTHP. If you reload, keep the muzzle velocity at 2600fps or lower for shots less than 150 yards. For rain or moderate wind, a Sierra matchking 175gr. For heavy rain, or brush, 180gr or heavier. Again, keep the muzzle velocity at 2600fps or lower for shots under 150 yards. You will hear lots of opinions on here, and that is all they are is opinions. This is my opinion. Try this info, and form your own opinion. Here is a whitetail, shot at 225yds, with a Sierra Matchking 168gr BTHP with a muzzle velocity of 2600fps. [/QUOTE]
