does anyone have load info or quickload info for loading 350gr and 400 gr cast bore riding boolits in the 416 ruger with imr 4198 and also reloader-7? in the newest lyman cast boolit book, they go from 5744 to 3031 in order of quickness in their load data, and only for 350gr rcbs boolits. since both powders I mentioned fall in between them, I figure a safe load can be had with both. I am looking to get 1800 to 2000fps, which is about what the other loads were listed for as start and max loads. so if anyone has any info I would appreciate it very much, thanks a lot, and happy new year!-Travis
