I think I will buy a block of ballistic jelly and see if I can get some slow mo shots into it. I am not trying to go hunting with the bare minimum, just genuinely curious. I asked some questions about .308 for black bear, and everyone told me to stay away from nosler ballistic tips, because they explode. I used a NBT to take a bear in December and it dropped like a rock with a devastating wound channel and pass through. Thanks for all the suggestions. I will keep you posted on the video once my gelatin block comes in. |
When you research something,know what you are doing before saying I am wrong.The average velocity using 110gr bullets in a .308win is about 3100fps.The average velocity using 165gr bullets in the same gun is about 2700fps.If you used a thinner jacket on a 110gr bullet at higher velocity,faster rpm,more than likely it would fly apart just beyond the muzzle because even tho one bullet is heavier than the other one is spinning faster and they weigh the same across the bullet.So,even if they are the same thickness the 110gr bullet has a thinner jacket for the velocity/revolutions per minute it is doing.Any time you are firing a bullet into wood or metal that it can penetrate,the hard substance will restrict expansion of the bullet,thus not allowing energy to spread out so the energy is able to keep the bullet in a forward motion.Wood is not wet flesh which allows the bullet to dispurse much of its energy outward thus taking energy away from the forward motivation,and the faster it is going the more it will expand and the more energy it will disperse sideways.As long as the heavier bullet has more energy the more energy it can disperse out and still have more energy to push forward.The light bullet,expanding more rapidly will disperse more energy sideways much faster. I have nothing against NBT,s and think they work ok for double lung shots on medium size game.If the game is bigger or a bone is hit I would prefer a partitioned or better yet bonded bullet.Just because a bullet works flawlesly once is no sign it will the next time,so I would opt for a bullet designed for more penetration/weight retention. sam.
