I recently acquired a Ruger No. 1 in 416 Rigby and what may be a lifetime supply of 400 Gr. Hornady Interbond Bullets. I am just thinking/dreaming about the possibility of a future Cape Buffalo hunt and wondering if the bullets I have are more than up to the task or do I need to consider loading a different bullet? Should Interbonds be relegated to smaller, less or non dangerous game and target practice?
