Good luck on caracal. I have always wanted one. Was usually out of quota or wasn't plentiful. Used an American audio predator electronic call before. Called in EVERYTHING except caracal. Cool watching leopard sniff around the speaker. Civet are nice too. I took several Genet with a .22 Hornet. Its quite often the little things that make safari so memorable. Shoot a few boxes of #6 12ga. at sunset around a waterhole for sand grouse is one to remember.
