The long range has a noticably thinner jacket for low velocity expansion. Theyre great for slow rounds like 30-06 that cant push the 210gr ABLR faster than around 2600fps, or for magnums for long range shots. At close range with really high velocity (3100+) sometimes they mushroom, sometimes they blow apart. Either way the animal still dies, but when it blows apart it tends to ruin more meat than I'd like.
For 400 yards and under with 7rem mag, I'd stick with standard Accubonds. Go to the long range versions if you are planning for longer shots or want the higher bc. I love my Accubond LongRange bullets, but they have their use case.
