Adewilde is right hate to tell you, but the only difference in shot placement is going to be in how steady you are, its not going to very from different positions, every time you fire your gun its going to shoot at almost exactly the same speed almost exactly where you aim it, as long as your steady. But remember never shoot a different type of ammo than what you sight in with, because this year we compared three types of shells sighting in, ballisitics were completely different from my cxp3's it explains why I missed my buck last season...
