What possible purpose would that serve?
If you have hit your target with an arrow it is now going to bleed out... and be quite dead. What improvement is that?
If you are in fact an idiot and believe you can kill something deader with a bullet than a broadhead, well, I am at a loss for words here.
Is this like a shaped charge for imbeciles? Filled with bird shot? The arrow having contacted the target will indeed go ahead and finish the job. Allowing a shot shell to fire at impact accomplishes notta.
Are these things sold with a roll of Sham Wow?
