Rob...Awesome comments!....Again....I will say it!

When you make a hole....the animal bleeds!.....its up to you to get it in the zone!.....
I was darn near hugging the button buck I killed (first with traditonal)with flint in 1998.......It was me & him that night...no friends....no cameras......the little button and me.....I looked at that hole that the flint made and could not believe my eyes......As the sun dropped I held the deer and told myself" oh my gosh...its not about the broadhead or bow...these things bleed when you poke ahole in those vitals....even with a stone....it only went 20 yards....I couldn't believe the stone did what it did!!
