My suggestion would be to not shoot through a heavy brush line. Try to cut a small opening through to use as a shooting lane. Some guns work better in the brush than others, but none of them will bust right through without changing directin or tumbling. That said, I use 180 grains in my '06, and just try to get a couple of inch wide opening to give me some margin of error. Good Luck!
