Been shooting the Nosler Partitions at big game for more than 40 years...7mm rem mag and 140 grainers...NO animal hit with one ever lived..every single animal recovered and those that took a few steps never took many!! What else can I say..the vast majority of bullet had complete penetration and always a good blood trail and I've never had one come apart and accuracy had always been around an inch at 100 yards with a factory rifle.
