For the record one big misconception is that all balistic tip designs are a general purpose bullet. In general ballistic tips (particularly nosler bt's and others) are not for shots under a 100 yards. Read nosler's site if you question this.
95% of the time when I hear about a hunter going sour on BT's its because they have shot some medium or large sized game in the shoulder at less than 100 yards, most within 70 yards and it failed to take the game down. BT's give rapid expansion compared to bullets such as the tried and true nosler partition. This rapid expansion is a big problem at close range and a big plus at long range. The rapid expansion make it easier for the bullet to expand when the energy levels are lower at 200 and 300 yards; where a design such as the partition may not give the best expansion.
Not all BT's follow this rule though...
