Re: arrow weight?
They can be of different weight, but that would be not a good idea. You should shoot the same weight whether target or hunting. Be more concerned about keeping the total arrow weight above the minimum recommended for the bow your shooting. Shooting an arrow with a less than recommended weight has the same effect as dry-firing.
