"Any BH can get little to no penetration if you hit the wrong thing in the shoulder area". Yes I agree, No I disagree. If no please explain
I typically blow right through the shoulder with slick tricks. In fact, I don't hesitate to aim for the shoulder if the deer is quartering to. I blew through both shoulders of a nice doe opening day this year. She ran off with one leg flopping around like she was shot with a rifle.
Granted I am pushing a lot of arrow and generate gobs of KE and momentum but I sure wouldn't aim for the shoulder with a flimsy mechanical.
