Well Dep,
since you have chosen not to answer, I went on a web searching the first 50 hits under a search for "deer wounding study" The only one that came up was the Camp Ripley Study.
The most comprehensive study on wounding ever made to date. It found that 87% of bow hit deer are recovered. The study only included conventional bows and no other weapon. The web address is

Wonder why I didn't find anything about a Texas study? Does one exist? If one does, why arent the results available on the net?
Maybe you can enlighten us on where you found it.
