The following is just a hearsay and I am selling it just as I bought it.

A friend of mine was sharing a camp in Zim (Save - Brooklands) with an US hunter that shot a Buff quartering towards him with a said bullet in .485 Lott. Shot was right on the point of a shoulder toward opposite hind leg. Bullet totaly disintegrated upon hiting the bone on the shoulder and never made it in the boiler room. They got the Buff later on, however that guy sweared that DGX will never see a DG hunt again...
