Go directly from Calgary to Frankfurt. From Frankfurt to JoBurg. From Joburg to where ever it is you are going to in Zimbabwe. Did this in 2006. The Air Canada rep liked hunters. Born of one, and married one. She told me to put my guns straight through, ahead of me. It worked. Carry plenty of small bills for African tips at the Air ports. Your PAL and facsimiles of your registration forms might come in handy.
