[QUOTE="jarnold37, post: 2515813, member: 29241"] Not to be disagreeable, but wold like to mention a few field trials I have learned from. A big high sectional density bullet will more than likely deliver a low hydrostatic shock event due to the bullet retaining its mass and not staying in the animal. In comparing two different calibers from the same parent cartridge, there is a big difference in shock. I shot several deer with 338-378 with 300 grain bullet. Many would run a distance before dying. Some bullets would pass through and even in shoulder shots, the deer never experienced a brain hemorage. Also have shot a large number of deer with 30-378. With the 180 grain bullet it would most always pass through with most of the bullets energy going out the other side. One shot killed two deer standing together as the energy was delivered to the deer standing behind. In the 30-378 I dropped down to 125 grain bullet and the difference is dramatic. Velocity is increased to over 4000 fps and the whole rib cage is blood shocked. They most usually drop without a step. Yes, the ballistic coefficient is much less, but no matter, as the increased velocity more than makes up for bc and out to 700 yards I still click less than with the big bullet. In the 338, went to accubond 180 grain and velocity is 3750fps and there is tremendous shock and usually no pass through. In 25-06, the 120 grain would pass through and deliver little shock and deer have run as much as 250 yards with lung shot. Dropped to 87 grain 3550fps and no pass through and much shock.
