I have been loading cast for a long tome, have a load for my 240 gr 429421 that is ok. I just bought a new Lee mold that was on sale, it is a 310 gr 430 dia mold, flatnose. I am looking for load data on that weight. I have found heavy load data, that is not what I want. I want to load for a NEF that is 1/20 twist, and want something in the 1200/1500 fps bracket. I thought the longer fatter bullet might prove more accurate, and I intend to shoot mostly wheelweight metal, so I am not after speed. I use mostly Blue Dot, 2400, RL7, and XMP5744 for my cast loads at present.
