The Harvester red measures over .507 loaded OD which is HUGE for a T/C bore. You want either Harvester black smooth (for under 300gr bullets) or the Black Crushribs. Those measure .503-.504 loaded OD.

BTW the black is not for .458s. Im not sure where you got that idea. The description is right on the website and pack. You can however use a .458 in the black crushrib if you have a loose bore.
