I'd like to cast for my#1 in 375 h&h. With the 12" twist I expect accuracy to drop off somewhere between 2000 and 2400 fps. I'm really trying to get jacketed performance out of cast in this cartridge not reduced loads. Jacketed in this rifle I shoot 270s at 2800 so if I can only get 2000 with 270 cast then it's not close enough for me. Also the lower bc of those lighter 375 cast bullets has them losing velocity pretty quick. A 350 gr bullet would be about 21-2300 jacketed so it should be easily equaled with a cast load. However in all my books the only 350gr loads I can find are for the barnes ttsx which is extremely long and I feel the data they have wouldn't be safe to use with a 350 cast. The mold manufacturer didn't have any data for a bullet that heavy. Does anyone on here have any heavy data? How good does quick load work. I've been thinking about getting it but I'd also need to get a computer too. Oh the mold I want is the accurate 38-345b. He recommended it to me because I was wanted heavy and it should be a good match for my throat dimensions.
