I also find that the 450 grain bullets recoil noticeably less than 500 grain bullets. Also the North Fork 450 grain solids are a little more accurate than 450 TSX, 450 Barnes solids, or 500 grain Barnes solids. The Barnes solids have a pretty good flat meplat themselves, though not quite as flat as the North Forks. The 450 TSXs are "spitzers" (kind of fat spitzers). Perhaps because of this, they shoot about 1" higher at 100 yards than the 450 North Fork solids, though both chronograph the same.
