All of these examples sound like shooter error to me. Bad hits on game, hitting a twig, jerking the trigger.
Plus, Berger "Target" bullets have a THICKER jacket than their "Hunting" bullets. So that point is moot too.
Plus, your grammatical errors are killing me. "AN animal", "Through", "You", "through", "right", "AN ethical hunter".
I will take a well placed target bullet over a poorly placed hunting bullet all day, every day. Actually, I will take a well placed target bullet over a well placed hunting bullet any day too. I know how my loads work.
