I did one two years ago. Short range, like 30 yds. Sneaky varmint under a barn. Stuck his head out and gave me just enough time to figure elevation and popped him between the eyes! DRT. But apparently, the bullet passed on down into its body/lungs? As I picked him up, blood started flowing out his mouth. And I do mean flowing! I tell ya, like Ohlongarm, these 17WSMs hit like a ton o bricks!
