What caliber? These are high performance bullets. The downside of hunting with such expensive ammo is that one may stint on sighting in.
I suspect they are Nosler Partitioned bullets, which depending on caliber, can run up to around a buck for just the bullet for reloading. Their effectiveness on game is widely, but not universally, acknowledged. CB
That Accubond is supposed to be a bad ass little bullet, but when it came to finding a load for my bear hunt, I went with the tried and true Partition.
