Matthew,I've usually shoot the same head as I do on deer which is a 4blade phantom or a 4blade Stinger 99% of the time....I've shot 2 with the bullheads,one of them turned out good & the outcome of the other wasn't so good(my fault,not the head)but I hear alot about them being kill clean or miss completly & that's not the case(human error is always a variable to deal with,at least for me..lol)....will I use them again...you bet I will...just have to take a few precautions & keep your shots close
