As stated in other conversations I shoot 105 hybrids in my 243. Have shot deer, wolves ,and coyotes with them in mass. They go in 4 or 5 " and then fragment rapidly. Internal damage is amazing. Sometimes an exit on deer, sometimes not. Exit on coyotes and wolves ranges from the size of a golf ball to the size of a tennis ball. It pretty much liquifies the internals. Some people don't like them because they cause too much damage, and blood shot.
