Just dropped one this morning. Only blood was where he, button buck), was standing. Ran 30 yds. down a lane and tuned into the brush. After 15 minutes, I went in, following the path of least obstacles. 200 yds. later i found him. Only a small amount of blood where he lay. 1/2in. entry, 2 1/2in. exit. The gun? .35 Whelen. First one I ever had to trail.
