Greetings, I am glad to have found this source of information. It is already been a valuable resource to me. I hope to continue to learn as I see there is a large volume of information to sort through. I currently have running and Oneida eagle H250 bow and a Pearson Sporter bow. Both I acquired for free and am learning how to shoot. I have extensive gun knowledge and use that for work. This will just be an extension of my ballistics learning.
