The old marginal hit was what I was referring to. Not in lungs or heart. My son shot one @ 475 2 years ago and it went maybe 60 yds but it was hit perfect. So what I am trying to come up with is something that will help out with the less than perfect shots. Such as a liver or gut shot. Perhaps put enough more hurt on em to keep the down even if not dead. That's what happen with mine this year when shot with a 338 wm. Bad shot but he went down where I couldn't see him and was still there for a followup when I got there. I know every shot is different but what factory ammo for a 7 mag would approach achieving this kind of results.
