I'm shooting a 61# Hoyt Protec, and pushing my Axis arrows at about 259 fps. I had a two blade rage go through the muscle tissue of the nearshoulder, through the ribs, both lungs, and stick in the off shoulder of a very large mule deer - couple of weeks ago in the mountains of Colorado. There was maybe 7" of arrow sticking out of the entry side. That's over 22" of penetration. You should be fine.
