[QUOTE="MagnumManiac, post: 1772635, member: 10755"] I went through the same thing with my build, a 338-416 Rigby Improved 35° shoulder. Load data is next to none. I found an old piece of info from an old Nosler manual that gave a formulae for working out safe loads using case capacity % and the birthrate of the powder...which is not constant anyway. Long story short, it went well and I was loading good hard data through the pressure trace without any hic-cups pretty quick. Capacity is a full 10-15gr more than the parent case depending on what powder type you use. I found RE33 to be the 'bees knees' and RETUMBO a close second. A few powders have proven to be finicky, RE17 behaves badly, as does RE25 with bullets lighter than 215gr. Most powders behave well with bullets of 300gr or more. Good luck with your new endeavour...that first trigger pull is a dandy. Cheers. [/QUOTE]
