Lots of different opinions but the facts are still the same, shot placement is luck because you can't predict when a animal is going to move, here are some wild rabbits and even when they are still you don't know when they are going to shake their head and scratch and at 30 yards there are also other factors to consider, think how far a rabbit can move from the time you pull the trigger.
10.5-11 ft/lbs is for fun plinking and competitions, shooting live animals is controversial when you have to rely on luck.
