Over my 60 years of hunting I have tried a various variety of bullets. Mostly when they are new and advertised as the greatest thing since sliced bread. The mono's, the Hornady's, Sierra Game King, and numerous others. (In fact the 162 grain 7mm Hornady SPBT is the most accurate bullet), I have shot in several 7mm rifles. There are always newer and better. But to this day the majority of my deer and elk have fallen to the Nosler Partition, and a new comer the Nosler AB. My favorite saying is that "if its not broken, leave it alone".
