Thank you for your input! The .475 I am considering is the .475 # 2 NE which is basically the .450 # 2 NE necked up. It runs about the same pressure as the 450 # 2 NE but has a .483 diameter bullet and as with many of the NE cartridges the same performance. I have a customer that would like the .475 mainly because he likes the huge 3.5 inch case and the total length of 4.5 inches. He thinks that is rather impressive and since he is a hand loader this is not a problem. Since I do not have any experiance with shooting game with these cartridges how do they stack up against the .458 Winchester? I know its reputation and I hope these cartridges do better, I know the .500 does and also the .470. I will be using my .450 # 2 NE on my third trip to Africa in 2007 but not on dangerous game so I value your input. Thanks again!
