Snidely,
If you keep moving your paper targets out progressively shooting 5 shot patterns at each distance, when you reach the distance where the 5 shot pattern has become about the size of a grapefruit, then you have found your maximum distance.
I wouldn't want to shoot at a deer in the field with a basketball size vital area with a rifle/load/scope combination that I couldn't hit a grapefruit with from a sand bag rest on a shooting bench.
From what I've seen, most people who can shoot 1" groups at 100 yards using a hunting reticle in a scope topping out around 9x, their group will get too big somewhere in between 300 and 400 yards. But just average hunters who use the same box of ammo for a decade will most likely not be able to do this well.
Your 95 grain partition ought to be able to penetrate well enough to kill with a hit at these ranges and beyond.
