Dillon's Crimp calculator is totally unnecessary. Crimps don't get measured. You can't adjust a taper crimp die to make different crimp diameters anyway.
"...reloading for my .45..." It's easier than it looks. The .45 ACP uses a taper crimp only and it's just enough to close the flare and keep the bullet in place. There's no actual measurement. However, 'enough' is usually so there's about a 1/16" or so of taper you can see shining on the case mouth.
You can forget the cannelure or crimp groove altogether.
"...don't experiment and use only loads from manuals..." That applies to everybody regardless of experience. Suggesting the start load is not a minimum load is exceedingly unsound advice and is totally unsafe.
