Q. What is the best round for hunting deer-sized game?
Many people consider the Winchester 64 grain Power Point (from the Super-X line) and the Power Point Plus (from the Supreme line) rounds to be the best deer rounds available. Predictable expansion across a wider-range of velocities is why most states mandate soft-point bullets for hunting and that certainly applies here. While military FMJ will certainly and quickly kill a deer within fragmentation range, it also tends to tear up a lot of meat and skin and leaves fragments all over the place which makes it undesirable for hunters. And it would be cruel to shoot a deer with FMJ outside the fragmentation range, as you would only wound the deer and it would likely suffer a long, painful death.
