From what I have seen, there are two kinds of hunting Ballistic Tips, both tough, but one kind is tougher than the other. The majority will typically retain around 50% of their weight. The other kind, the models I already listed with VERY heavy jackets, will typically retain at least 60% of their weight.
Seems I remember you (or someone) saying the VERY heavy NBT's tend to be in weights not covered by a corresponding NAB.
