Hi CRS,
About TUG, maybe they are not tough as a Barnes X but TUG are very tough bullets created by Wilhelm Brenneke to be used in Africa, they are twin core bullets, where the first core tend to expand well while the second core in hardened lead, blocked by jacket lock, goes through game like a Partition or a Swift A-frame. Speer surely took inspiration for the first Grand Slam from TIG and TUG bullets. Lots of African game was killed by such bullets in 9,3x62 or 64. Friend of me use them with authority on cafer and equinoxialis buffalos for years. But think they must be hard to find in the US and very expensive.
