Drew very good report and photos.

This is just my speculation. If I make it to Africa after cape buffalo I would carry Woodleigh 410Grn RNSN for my 416rigby and the Hydros. The SN for shots that may cause collateral damage on pass through.

Huvis I think you might find that the damage is soft tissue damage not a massive exit wound like you get with soft nose. Going by some reports I have seen of the Hydro's it is much like the entry but inside is a mess. Drew or other users of the Hydro's might be able to shed more light on this.
