I don't know what you expect in an exit hole, I would like to know what you consider small. A deer that only went 15 yards and dropped is a well hit deer and not a deer that would get away. Some deer will drop in their tracks, some will not, I have had many of both. I really don't get your complaint about the federal ammo you used because your deer went 15 yards before it fell. They all do not fall down like they were pole axed. Yesterday you wanted to know if a bonded bullet would do what you want because you had a deer drop 20 yards after it was hit and one by your son go 100 yards. I am trying to understand what you expect. Ther exit hole doesn't mean all that much, a lethal shot is a lethal shot and by the time a bullet makes an exit hole the damage has been done on the inside, the lungs will still be soup in the chest cavity regardless of the size of the exit hole, if bone is not hit, it is not unusual for the exit hole only to be a little larger than the entrance hole. A huge exit hole with a bad hit doesn't mean a thing and a small exit hole with a good hit doesn't mean much either. It appears you are looking for a magic bullet, there is no such thing. I suspect you do not have much experience based on your posts but as long as you are using a cartridge from a reputable manufacture of a large enough caliber, the hunt for a super bullet is a waste of time, placing the round in the right location in the animal is what you want to count on.
