I used these quite a bit back in the 1980's in the 180 grain .308 and the 150 grain .270. Got good but not great accuracy out of them. Terminal performance was really good. They make a bigger hole through the middle of the animal than the Nosler Partition or the Barnes X, yet still have very good penetration and won't come apart if you hit big bone. My only complaint is that the BC isn't very good - which isn't really an issue until you get out there about 400 yards or so.
