You need to hit em in the right place . If you`ve shot a rabbit 2-3 MORE times and its still running , you should know that your not hitting the mark . Untill your 100% you can hit a your target , you should`nt even be looking for rabbits . You say this has happend a number of time , it should have only happend once before you STOPPED . There is no excuse for continually shooting live and leaving it to die , a kill should be clean and precise . PRACTISE , PRACTISE , PRACTISE , thats the only thing you should be doing .
