Do you feel the ML bullets have a thick enough jacket ? From what I understand the 454 and 460 both need a special bullet with a thick jacket , like the Hornady XTP/ Mags.........I believe Grumlkin, not sure I spelled his ID right, uses ML bullets in his 460, he was well satisfied with them. I was gonna try them, but chickened out...I'm just not sure about the pressures. Maybe someone can help us. Mike
