i don't think that the mistake was killing the button bucks if that is what you set out to do i think the mistake is that he missed with six previous shots because he did not tune or practice with his bow or broadheads then he went out and brought mechanicals and instead of practicing to see where they fly he just went out in the field and took luck shots one was so bad that the deer ran 100 yards who knows how many deer he killed and did not find before he got these two
