"150 grainsof powder and a 245 or 295 grain powerbelt will NOT blow up with a lung shot."

Sorry, this just isn't supported by the facts. You may have gotten lucky with one, but I have seen numerous shots that did not. The one I described earlier was a double lung shot. Absoloutly exploded the lungs. Deer went about 40 yards in some very thick cover and was difficult to find. Bullet, or the majority of it, was just under the skin on the opposite side.

I've seen lots of deer hit with PBs, lung shots, spine shots and shoulder shots. Around here, the end result has always been the same. A blowed up bullet. Sometimes fragments make it out the other side, but not really a bullet with most of it's mass. The main reason for this is that everyone watches on TV and reads about them and two things happen. First, they hear about "magnum" loads and assume more is better and second, their over zealos attitudes and mouth gets them into the same mode; more is better. End result is they stuff 100 or 150 grains down the muzzle, find that the bullet is very accurate with this combo and assume that the terminal perforance will be the same.

There are clubs in the south considering banning PBs because of this performance. I have heard of outfitters that refuse to allow clients to use them and we are reviewing them where we hunt.

I think the 1200 fps area is probably an excellent data point. Better is slow to a point, faster is bad at a point. Every bullet has an optimal terminal performance range. I don't care whether it is a Nosler Partition, Sierra Game King, Shockwave or Power Belt. Keep them in this range and it is unlikely that you will be dissapointed. Any bullet pushed to fast will blow up on impact and the PB is probably in the 1200 to 1300 fps range.
