I just joined this forum. I have been reading the articles here for a while. I am planning a trip to Africa for 2012 / 2013. So as you can imagine the depth and breath of information is overwhelming - but highly educational and fun. Thanks. I have a Kimber 84M Classic in .308 topped with a Nikon Monarch 2-8x 32, being carried by a very light sling. Ringing wet and fully loaded it is just under 7#. I can shoot various Hornady 150 / 165 gr ammo with it into 3-shot groups of 0.75" at 100 yards off of sand bags. My handloads have provided 0.5" groups here and there. I am also considering building a custom 300 WSM - for this trip and perhaps it can double for NA large games (Elk, brown bear, ...). This will be a 22 - 24", Carbon-barreled, carbon-stocked rifle weighting in the 9# range - depending on scope. Is a 300 WSM needed for african planes - especially larger ones? Will my trusty 308 win do the work with the proper bullet selection? In an emergency, will 300 WSM even be available in most african countries? I am not a fan of large calibers that go BOOOOOM and take out your forehead, shoulder and ears. Nor do I enjoy dragging around heavy rifles - without cause. I have seen folks bring xxx magnums to the range to zero them in for antelope hunting in Wyoming I much rather carry an extra bottle or two of water. Thanks for the feedback.
