I am guilty of brush bustin. With success. But I try never to do it. I usually use a slug gun. What I noticed on my own tests with a bunch of brush and a target 10ft back, is the bullet can keyhole or tumble. So if you have a bT or a softpoint probably won't matter. Its going to make the bullet unstable. If you ever shot an arrow at a buck, and hit a little twig, you see what happens. I have had arrows shoot 20 degrees or more out of line of shot with little twigs I couldn't see in the early season.
