Number 2 is my pet peeve of the 1s I hear. Another is boresighting will work as sighting in. Also just because a rifle shoots 1" groups at 100 yards, it'll group 3" at 300 yards.

1)The bullet went through the animal so fast that it didn't have time to expand.Reducing the velocity will give it more time in the animal,so it will expand more.
2)I can't hit a target off of a rest at the range,but I am a deadly shot on real game from field positions.
