Im sure they can frag since it is only a Rainier bullet. They used to sell them in just a HP but stopped after getting the contract with Harvester. You cant buy their 40-200gr any more either for the same reason. Ive turned a 50-300gr Rainier into a pancake and i was far from my max load. The same weight GoldDot 50A&E held up just fine in the same load/media on the same day.
