I have shot a pile of whitetails on crop damage shooter permits and hunting , well over 50 deer with the 7mm 139gr. SST bullets. I send them at 2950fps and they have all peformed well. I think most problem come from over driving them. Most bullets don't hold up well if if driven over thied designed velocity range. The guys shooting light for caliber bullets out of big magnum rifles are setting themselves up for failure. Also , IMHO the barnes bullets are a poor work around for a bad california law. They have no place outside of a no lead zone. Putting the heavier than lead metal in the base is a good idea but the price is crazy high. As for meat damage , don't shoot them in the shoulders and expand the bullet in good meat , shoot just behind the shoulder and destroy the back of both lungs.
