In Iowa the big wigs of the DNR advocate using blunts for turkeys, 9/16" or larger. I talked to a fellow that up to that point killed three. Two with a type of HTM with a concave front and a nickel glued to it and the other with a bludgeon on a cedar arrow with a tip weight cone on the arrow. He said that a direct body hit turns the insides to mush and the birds 'went down hard'. He was shooting a 65 pound recurve with a 27" draw. I have been hunting pheasants with various bows since I was 12 years old, nearly 60 years, the first bow was a sinew back ash billet made from a strip of wood that was lightening cured and dried from our neighbors ash tree. I used those free Hi Precision 3 blade broad heads with that bow, but since most have been taken with various blunts and a couple with bludgeons. Even a sharp three blade broad head is no guarantee that a cock will not run and hide in cover when hit. I am convinced that a blunt or bludgeon is far more deadly on rabbits than a broadhead. Once with a squirrel, I pinned him to a tree with one of those original worthless Wasp broad heads. The squirrel kicked and squirmed and then hung lifeless. I hung my longbow on a branch and unscrewed the 2019 from the head. The squirrel fell to the ground, jumped up and shot up a large tree, never to be seen again, Wasp head is still in that tree. Two days later while hunting with a 64@26 longbow, I took a shot at a squirrel way up high in the branches with a 2018 pushing anHTM with a blunt in side. I hit the moving squirrel, he was stone dead before he hit the ground. A flying pheasant will always have a varied impact absorption status, depending on direction and speed, but on the whole, I do not think they are as tough as some claim. A less than direct hit makes the bird seem tougher than he really is.
