It depends on more than your bow weigh. You say you' re using Rocky Mountain Broadheads. Which one, fixed or mechanical? If it' s mechanical you might definitely have a penetration problem with you short draw and average poundage. Secondly, if your arrows aren' t flying true and they' re hitting at an angle or fishtailing or something like that, it' ll steal a lot of you power....again penetration problems. So, we can' t really say. You should beable to get a pass through under the right conditions, but not necessarily so. Another 5 pounds on your bow would give you more ump, but it would probably throw you into a different spined arrow or smaller broadhead to maintain spine. I didn' t bother to look all your data up on the arrow charts, I' m just assuming you have what' s right now. I guess that might be a mistake too.
