Over the last few years I have been trying some different 2 blade broad heads and think I have noticed something kind of odd. It dose not happen all the time but I have noticed more times than not it seems you get a high amount of capillary bleeding. What makes me believe this 8 or 10" ring around entrance wound and sometimes the exit. This ring almost looks like the deer was shot via rifle. To see this the deer needs to be skinned. I wish I would have taken pictures of this but didn't really realize the difference until just recently while doing some post season recaps.
Well I am glad I I'm not the only one that has seen it. I thought it might have more to do with the way it cuts due to it not being as noticeable on exits. I was thinking this was due to loosing some of its sharpness. It definitely could be due to rotation. Considering all the deer I can think of over the last 3 years have been shot with the same six pack 1000 grain arrows, same bow and all between 6 and 15 yards. Just a final thought wouldn't you be just as likely to see bruising from double bevel when it's rotation is stopped?
