A couple failures from the first version of the 7mm 150 on the shoulder of an elk from a 280 at about 250. Eventually a neck shot put him down. My brother was doing the shooting. This was early or mid 90's. We still debate why he kept shooting for the shoulder, instead of aiming 6 inches to the right. Both bullets 'varminted' in the meat of the shoulder. It was a mass of blood and mess, but there was no evidence that any fragments made it into the chest cavity, or if any did, there was no obvious damage. No idea of the impact velocity, but I do know that chrono'ing more recent fodder in that gun suggests velocities more associated with 7-08 than typical 280. He won't use BT in 7mm to this day. He loves them in 30 cal though, particularly the 180s.
I'd like to get my hands on some old 30 cal 150s or 165s for a 30-30 Contender. They rated them for opening at 1600. Not sure how much different today's version is, but Nosler doesn't seem to want to budge from the current 1800fps min.
