I lost a doe today. Shot her at about 30 yards with my 45-70. She ran for over 600 yards before crossing a fence onto property that I don't have access to. (They won't let you cross the fence to recover game. You have to have the landowners OK to do that in Tennessee.) The blood trail was nice large frothy pink blood from a double lung shot. Why she didn't go down I'll never know. 405 grain flat nose cast out of 50/50 WW/pure at 1450 FPS. I am still sick over losing this deer. It's the first one I ever lost in all my decades of hunting.
