"Frontier Spartan is a range of monolithic hunting bullets; perfectly manufactured from pure copper". The Spartan range are premium hunting bullets. I started using the Frontier bullet this year and had great results on a giraffe and a blue wildebeest. Wondered if anybody hunted dangerous game with this product? If so, would you recommend it or must one stay with the traditional well known products like Barnes, Nossler, Swift A-frame etc. I have a opportunity to hunt a buffalo cow in the not so far future and have to do the necessary prep before the hunt. This will be my first big 5 hunt and don't want to messed it up... but i would like to use the spartan... Any advise please!!!!???
