One great bullet that Nosler & Winchester developed together, yes heck of a stout bullet that suffered from low BC , but they performed great breaking big bones and shoulder blades, it out performed the Partition which says a lot!, yes to hard for deer but it was meant to break big bones and drive deep , I’ve still got a magazine write up on them when the Winchester WSM’s came out they shot them in Australian buffaloes, useing the 270 WSM,7WSM& 300WSM ‘s in Browning & Winchester bolt rifles . Performance was 2nd to none , great write up with pictures .
