I've been searching but not finding much good information. I'm going from jacketed to powder coated cast bullets in my 1956 Marlin 336 .35 Rem. It's been fire lapped and shoots pretty well with standard 200gr RN jacketed bullets and 36gr of IMR3031. I'd like to duplicate the accuracy and velocity with the Lee 358-200 I have. I've slugged the throat/bore and am working on getting the bullet diameter up to suit it. What I can't find is "high velocity" load data for powder coated bullets, which I am lead to believe should be able to be pushed to better than 2000 fps? All the book data I have from Lyman and others limits to relatively quick pistol powders and 1400-1600fps velocity. Was hoping there would be a rule of thumb for going from the jacketed data to cast with this type of bullet. I realize the technique is fairly new and probably not a lot of experience with it yet compared to traditional lubes, but one of the reasons I went down the path was to be able to maximize the 35 rem velocity with cast bullets. If successful, I'll branch out to other rifle calibers.
