[QUOTE="Jud96, post: 949229, member: 69478"] I would also say that the .243 AI is more efficient than the .240 Weatherby, maybe not as fast but a lot easier on brass and powder. My Dad has a .240 that he loves but he got all of his brass back when you could find it and afford it. It will push a Hornady 87gr HPBT at 3500fps out of a 26" barrel with 55grs IMR 7828 but the .243 Improved will launch the same bullet at 3400 and it burns about 10grs less powder when using IMR 4350. Case life is probably better with the .243 AI as well. He never shot any 100s through his rifle but I would venture to say the .240 will push a 100gr slug at 3250fps and the .243AI around 3150fps so still only 100fps slower with around 10grs less powder.
