All, I am new to the site, and going to be new to double rifles, as part of a five year plan to hunt africa (the first several years saving, planning, and shooting) 1. 450 NE, 450-400 NE, or 470? Also, in the two 450's, 3 or 3.25"? The two animals I want most are kudu and cape buff. I want a rifle I can go back with and get something bigger someday, if possible. I am a big believer in "use enough gun" but a bigger believer in "use all the gun YOU CAN SHOOT WELL" I use a 375 h&h for moose currently, but want the nostalgia of a double for Africa. Will the 450-400 "stop" a buff? Could I use it if I can get back for an elephant?--or do I need to go bigger? Also, I dont handload, so which has factory rounds available? It seems I can find 3" in the 450 and 450-400, but not 3.25"? 2. I have heard a lot of bad about the Sabatti rifles, so is there much differnece in the Merkels, Searcy's, or similar price range? Or, maybe a place to look for a used higher end gun? (10-12k, with a possibility of going up to 15k if I find a "can't live without"--would obviously prefer less expensive, but not at the expense of functionality) One more--wrong forum, but....plains game rifle--300 h&h enough for kudu? Thanks for any replies. I realize that a lot of these (probably all) questions have probably been asked and answered over and over, but I am not the most computer smart guy out there.
