The short of it: for various reasons (OK the wife said "NO") I can't cast in my house or yard or the garage. I have a Parker Hale .45 Volunteer Rifle; recommended bullet is 560 grain .451. The closet available retail cast bullets are for the 45-70 at .458, so the question. Can I resize the .458 to .451 just using a .451 sizer die or do I have resize progressively, .458 to .456, .456 to .454, etc? I know Track of the Wolf has .451 cast bullets, trying to save some $$$.
