RE: You can have 3 calibers, nothing else...
Bigbulls,
Easy, upon securing the safari (usually 6 month to a year in advance with half the money down) I would do one of the following four to remedy the problem:
**Sell one of my (imaginarily limited) three and replace it with the Big Bore needed for the trip, or
**Borrow a Big Bore from a friend, or
**Rent a Big Bore in Johannesburg upon arrival, or
**Use the PH' s Big Bore " camp rifle "
Since folks " rifle luggage" don' t always arrive/check through with the passenger -- PH' s are already way ahead of the game on that one -- if you have the money for a safari, they won' t let a little detail like the lack of a rifle stop you).
