Things have a been tight for the past few years, but look like they might start to get a bit better soon. If so, I would eventually like to book a trip to shoot plains game in Africa. I currently use a 6.5x55; would this be OK, or do I need to add the cost of another rifle into the equation? If so, what calibre? 30.06 must be amongst the contenders, and has the bonus of readily available factory ammunition.
