I’m wanting to purchase the Lee 340 grain 45-70 mould, but for the life of me cant find any load data in my books: Lee Second Edition, Lyman Reloading 49th edition nor the Lyman Cast Bullet 4th edition. Anyone cast this bullet…? Any load data? OR recommendations on a 300-350 grain mould to start out. I know Lee makes a 405 grain mould and there is plenty of info on them, but trying to shoot a pleasant paper punching load first. Thanks for any and all info.
